@aakashgupta MCP is a brain drain. Someone should come out with a tool that continually learns and updates weights on the fly. No batch retraining.

Every MCP you add to Claude Code is a silent tax on every task it runs. Most people are excited about connecting as many MCPs as possible. More tools, more power. But each MCP consumes thousands of tokens just by existing in the context window. Before Claude writes a single line of code, it's already spent reasoning capacity holding connection details for tools it might not even use on that task. CLIs solve this completely. A CLI sits on your machine. Claude calls it directly through the command line when needed. Zero context cost when it doesn't. The hierarchy, confirmed by Karpathy: CLI at the top, API in the middle, MCP at the bottom. The practical difference is stark. Google Workspace MCP is notoriously painful to connect and maintain. The Google Workspace CLI just works. GitHub CLI makes Claude aggressively competent at repo operations. Vercel CLI handles deployment, logs, and environment variables without burning a single token of passive context. This is the part most Claude Code guides skip. They teach you which tools to connect. They never mention that how you connect them determines how much thinking capacity Claude has left for your actual work. The context window is the scarce resource. Protect it.

@toddsaunders Same thing will happen with LLMs. They will commoditize. Just like you can go to any gas station and fill up.

Every major platform shift (that’s happened in my lifetime) follows the same pattern. Something expensive becomes cheap… and the entire industry scrambles to restructure. When compute got cheap, mainframes became PCs. When infrastructure got cheap, server rooms became AWS. And when customization is getting cheap, SaaS becomes AI native software. For the last two decades we built standardized software and made every customer conform to it. We then created a $380B implementation industry to close the gap. That’s not a services industry. That’s a product failure priced as a feature. In SaaS - vendor builds one product, every customer conforms. In AI native - product conforms to each customer and improves through use and inference. The customization margin migrates from services firms to software companies. The next two decades will be about conforming to customers, not them conforming to the software. You can either embrace this and build with it, or you can push back and have your company die slowly. The choice is yours.

@seanspicer Does anyone really think Israel will stop? I'm in the Joe Kent camp. Give them enough allowance to defend themselves and that's it. Otherwise the holy war will continue.

the next time someone talks about out NATO allies consider how our "allies" are acting now regarding Iran: ✅Spain refuses to allow use of their airspace ✅ditto for France ✅Italy declined to let U.S. war planes land at a base ✅ Britain initially refused to allow the US of their bases

There is a huge opportunity for resourceful and entrepreneurial talent within organizations to go in and reimagine workflows for a world of agents. The way you automate work with agents requires real work. It means setting up unstructured data in a way agents can easily access, learning the workflow and processes and creating skills or plans for agents to leverage, connecting disparate systems together, and likely changing the process itself to support getting the agents the need to do much of the work. Then you have to design where humans will play a role to oversee the workflows, how you validate the work, and so on. Most of the gains you see from coding don’t take this level of effort because the agent knows more, it gets context more easily, and the users are technically. But for the rest of knowledge work there’s no way around this; there’s really no way to shortcut any of this work. It has to be done by a person or people on the team. You will see a huge growth of roles within enterprises, and people that specialize in this will be hugely valuable in the economy. Great way for early career folks to make a huge dent quickly as well.
Alex Lieberman@businessbarista

Contrarian take: there's never been a better time for early career professionals to command the attention of leaders in their company. How? Become the AI Guru in your company. Every co has a few of them & they instantly earn visibility with the c-suite... If you're an SDR, map out the inbound SDR process end-to-end in your org and build an AI agent on Vercel that automates several/all steps. If you're an engineer, evangelize Claude Code & lead enablement workshops, helping other technical folks understand everything from hooks to worktrees to claude[.]md. If you're a growth marketer, build a paid media workflow that mines creative ideas from reddit, spins up 100s of ads using Nano Banana, sets up the campaign on Meta, and drives traffic to custom landing pages, so you can test ad spend far more efficiently at scale. You could be the most junior person in your company, but if you're truly viewed as the AI Guru, you are wildly valuable & have way more leverage than you think.

Kid graduated from state school CS program last week with a 3.91 GPA and $174k in student loans Applied to 1,247 entry-level positions since February Got exactly 4 callbacks. Zero offers. Every rejection email mentions they're "moving in a different direction" or "pausing junior hiring" His algorithms professor keeps asking why he hasn't landed anything yet Meanwhile his university career fair had 12 companies show up. Down from 89 in 2023. The brutal fucking truth: every "junior developer" posting now requires 2-3 years experience because companies are using AI to eliminate onboarding costs His roommate who dropped out sophomore year to flip houses just bought his second rental property The kid spent 4 years learning data structures while the industry decided humans who need training are too expensive His loan payments start next month $2,100 due every 30 days for the next decade For a degree that qualified him to compete with ChatGPT for jobs that no longer exist

Recruiter with 15 years in the game just pulled me aside at a coffee shop and started shaking Not metaphorically. Actually shaking. "I've placed 2,847 engineers in my career. This year I've placed 11." She used to get 50-80 applications per role. Quality applications. Now she's seeing 3,200+ per posting. "Senior React position posted Monday. 4,847 applications by Wednesday. Half are ex-FAANG. A third have advanced degrees." The ghost rate is 94%. Companies schedule first rounds then vanish. No explanation. No follow-up. "Three clients told me they're 'pausing human hiring indefinitely' while they 'optimize their AI workflows.'" A Series B fintech just told her they replaced their entire 23-person engineering org with 4 AI specialists and offshore contractors. "The CEO said they're building faster than ever. Same CEO who spent $400K on my placements in 2022." Two major enterprise software companies have gone 8 months without hiring a single engineer. "I'm watching the entire profession disappear in real time. 15 years of relationships. 15 years of expertise. And I can't place a senior architect with 12 years at Google." She's thinking about selling insurance. The woman who used to have VPs on speed dial is applying to work at her kid's elementary school.

Benchmarks are one thing. Shipping product is another. I'm running Claude Code with Opus 4.6 as my entire dev team — built and deployed 3 commercial apps as a solo non-developer founder. The gap isn't just open source vs frontier. It's "can it hold context across 100+ files, manage state, and ship production code autonomously." That's where Claude Code is untouchable right now.

Over the past week, you may have seen an anonymous post about Delve. While we responded to it in a day, we want to provide more details about what’s true, what's not, and some changes we’ve made. There’s one question behind everything: did Delve fabricate compliance evidence or issue fraudulent audit reports? No. We did not. → Delve is an AI compliance platform that connects customers with independent auditors. We are not an auditor, just as tax preparation software is not an accountant. We have never signed an audit report. → Using default templates for our customers, just like any other compliance platform, is not “faking evidence.” These are meant to serve as a starting point for customers. → Delve does have automation in the platform, with 600+ automated integration tests, an AI Copilot to guide customers through compliance, AI code scanning, and more. -- We built Delve to accelerate innovation by bringing AI to compliance. In doing that, we pushed hard on automation. However, we now realize we didn’t provide enough clarity about what is automated, what is customer-provided, and what is independently audited. We have been working relentlessly to make improvements over the last week. -- On our auditor network: Delve connects customers with independent auditors. Some customers choose their own auditors, but many use firms in our network. Questions have been raised about some of those firms, including ones used by other platforms. Going forward we will set a higher bar in how our auditor relationships are structured and how the process is experienced by customers. Delve is rebuilding our auditor network, removing firms that don’t meet our standards, and offering complimentary re-audits and penetration tests to every customer. On platform templates for our customers: Delve provides default templates, just like many other platforms, for policies, board meetings, risk assessments, and more. These are designed to be starting points only. We should have been more explicit about how they are meant to be reviewed and customized by customers. We are making that indisputably clearer within the platform. On draft audit reports: Third-party auditors are responsible for independently reviewing all evidence and issuing final reports. We built automation that interacts closely with independent audit workflows to help expedite the process on behalf of our customers. However, this contributed to confusion about where automation ends and independent judgment begins. From now on, Delve will no longer automate these parts of the process. Furthermore, customers have a direct line of communication with their auditor to enhance transparency in any audit communications. -- We started Delve because we went through compliance ourselves and saw how slow, expensive, and manual it was. To anyone that wants to sit down and discuss our product philosophy and improvements, please reach out and let’s chat about it.

@JasonrShuman What about a model where a knowledge worker trains and deploys an agent(s) like a new hire FTE but with a continual learning loop where the agent gets smarter as it "learns" and weights are updated on the fly.

Coatue just put a number on what we’ve been seeing at seed for 3 years. Software = $0.2T market. Services-as-software = $5.5T. 25x. The shift is from selling tools (per-seat) to selling work (per-output). This is why the best vertical AI companies don’t compete with software incumbents. They’re compete with expensive service providers, BPOs and high turnover labor. A $2K/month AI agent replacing an $80K/year agency is the new business model.

Master Electrician here (IBEW Local 369, EVITP certified). You’re not missing anything — you’re dead on. I built ChargeRight because I saw the gap firsthand. Every EV charger install starts with a load calculation, but most homeowners get told they need a $5,000+ panel upgrade when they don’t. ~80% of homes can handle a Level 2 charger on their existing panel. So I taught myself to code with AI and built a $12.99 tool that does the NEC 220.82 load calculation for them in minutes. No contractor markup. No unnecessary upgrades. Blue-collar + AI isn’t coming. It’s here. evchargeright.com

AI will create a blue-collar super boom bigger than the Industrial Revolution; technicians, electricians, welders, hvac, plumbers, construction, roofers and new businesses will be created to manage it all resulting in a further expansion of our middle class wealth. Get ready! Expansion follows in the wake of all breakthroughs & the bigger the breakthrough the bigger the expansion. What am I missing?

Founders: I know it seems like on X everyone is killing it, massively rounds, AI this, AI that. But if you aren't killing it ... 😢Not sending investor updates is not the answer Investors expect tough times. They may be critical, but they expect it. But everyone checks out when you miss more than one investor update.

BREAKING: Anthropic’s Claude is stealing OpenAI's market share 🤯 OpenAI products had over 90% of U.S. business AI chat spend in April 2025. By January 2026, Anthropic products were at approximately 68%. Claude Enterprise alone was about 45%. At the same time, Anthropic ARR went from $1B in Dec 2024 to $9B in Dec 2025 to roughly $20B by Mar 2026. Claude Code is already at $2.5B ARR. 500+ enterprise clients. 80% B2B revenue share. Consumer attention still matters, and Claude by Anthropic reached 10.0M mobile DAUs by late Feb 2026, but the bigger point is where the money is coming from: companies that know how to use Claude inside real workflows. AI adoption splits into 2 camps: 1) teams that “try AI” 2) teams that redesign work around it Anthropic’s edge looks less like hype and more like workflow depth. Dario Amodei’s company didn’t just ship another chatbot. It built a product stack pulling serious enterprise spend away from ChatGPT Business, ChatGPT Plus, and ChatGPT Pro. If you’re a founder, the lesson is concrete: knowing how to use Claude is becoming an operating skill. The winners won’t be the people with access to AI. They’ll be the teams that turn Claude into process, output, and revenue.
