@DanielSmidstrup Right now I’m building a testable way to validate AI deep research reports by grounding them in conversations with real users. Market research conclusions should be verifiable just like how coding agents are because they can test their output.

@Vapi_AI wondering for the curious out there: how often does the problem with deploying voice agents really just boil down to working with legacy systems of record?
I’m curious how real-time voice agents that need fast responses get them when they need to work with backend systems that are slow and unreliable.

@alive_ Agree with most but you still need to write code by hand for most technical coding interviews. LLMs are still strictly forbidden for most modern SWE interviews.

Barbell strategy for killing it in an age of superhuman AI:
Simultaneously get as close to AND stay as far away from AI as humanly possible.
1. Get close — play with AI models, use them to help you think, ask them to teach you about the world, get them to help you create, work with them to write code, understand what makes them tick, embed them into your everyday life, have fun.
2. Stay far away — learn to tell stories, make eye contact, build a team, lead with courage, connect far-flung ideas, build lifelong friendships, debate persuasively, think forbidden thoughts, handwrite ideas, confess your fears, fall in love.
Spend less time trying to master mental transformations that are purely mechanical — building spreadsheets, analyzing trades, balancing accounts, writing code by hand, following playbooks, searching for needles in haystacks. These are the emerging no-man's land, squarely the domain of AI.
Venture to the extremes. That’s where all the fun is anyway.

Inspiring backdrop to build against at the @AGIHouseSF! Building something great for the Build A Company hackathon for this weekend. Stay tuned!

Just finished reading the chapter on Optimism in the Beginning of Infinity by @DavidDeutschOxf.
A quote to start off 2025:
“For if any of those earlier experiments in optimism had succeeded, our species would be exploring the stars by now, and you and I would be immortal.”

@svpino I’ve typically seen integration tests used instead when you don’t use mocks.

I think of Starbucks as another fast food restaurant similar to McDonalds.
The last time I was in one they had taken all of the chairs out of the restaurant and it was very dirty. I don’t even think they had a bathroom that was available to the public.
And this was in an upscale neighborhood. Think +$MM homes.

Starbucks has gone to crap.
I visited a Starbucks recently. It was nothing like I remembered:
- Stores are empty—and some are kinda dirty and messy.
- The community cafe vibe is gone. People are in and out. Purely transactional.
- Drinks aren’t interesting anymore.
- Staff are less friendly?
Take a look: their stock price barely moved in the last FIVE YEARS (+2%).
So sad to see such a legendary brand go to crap.
The beginning of the end for Starbucks.

@elonmusk The replacement number is 2. Although concerning, as long as we don’t go below that, it’s not contracting.

@loganthorneloe @svpino The lack of focus on code is precisely the reason the software sucks most of the time.
Higher quality code is usually the solution to software that sucks.
Software that’s solving the wrong problem isn’t something that an AI can solve with more auto-generated code.
English

@svpino I think it'll completely change the role of a developer.
Less of a focus on code. More on actually solving problems.
English

@svpino Curious if you have any high-profile examples of software that should be improved.

@dibuenio Stop doing whatever you’re doing and do something enjoyable. Get outside and enjoy the fresh air.

@sama What sorts of problems can ChatGPT Pro solve that ChatGPT Plus or sonnet can’t?
English

almost everyone will be best-served by our free tier or the $20/month plus tier.
a small percentage of users want to use chatgpt a TON and hit rate limits, and want to pay more for more intelligence on really hard problems. the $200/month tier is good for them!

$200/month, damn... . Maybe a student discount... , @sama?

@ericweinstein Why besides wishful thinking? The universe doesn’t bend to our hopes and desires. I’d love to believe this however the rational part in me fears Einstein’s speed limit will remain.

My co-founder and I live in NYC making $40K / year as YC founders even after raising millions.
That's $9.61 per hour (based on 80 hour work week).
Many people think that if a founder raises millions, it makes them a millionaire.
But here’s the reality of being a founder:
- I am on my parent’s health insurance
- I share a 1 bedroom apartment with my co-founder to cut costs
- I eat microwave meals because they're fast and cheap
- I take the subway everywhere instead of ubering
We could be making 5-10x more in our past corporate jobs.
When we started @VectorShiftAI, a no-code platform that allows anyone to build AI workflows, we decided that we needed to fully align our incentives to growing the company.
We wake up every day thinking about our users instead of how much money we are making this year.
Founders need to be all in.
