I met today with the founder of Starcloud and I realized this is going to be one of the biggest engineering projects of our era. When you look at the tradeoffs, it seems inevitable that all the GPUs are going to live in space.

I've never felt this much behind as a programmer. The profession is being dramatically refactored as the bits contributed by the programmer are increasingly sparse and between. I have a sense that I could be 10X more powerful if I just properly string together what has become available over the last ~year and a failure to claim the boost feels decidedly like skill issue. There's a new programmable layer of abstraction to master (in addition to the usual layers below) involving agents, subagents, their prompts, contexts, memory, modes, permissions, tools, plugins, skills, hooks, MCP, LSP, slash commands, workflows, IDE integrations, and a need to build an all-encompassing mental model for strengths and pitfalls of fundamentally stochastic, fallible, unintelligible and changing entities suddenly intermingled with what used to be good old fashioned engineering. Clearly some powerful alien tool was handed around except it comes with no manual and everyone has to figure out how to hold it and operate it, while the resulting magnitude 9 earthquake is rocking the profession. Roll up your sleeves to not fall behind.

This feels directionally right. An agency comes in for a few weeks, maps how work actually flows, and installs claude skills/agents that handle reporting, follow-ups, checks, and coordination. That replaces work spread across a few roles that might cost $250k–$400k a year. The company pays once for the setup, keeps the system, and only brings the agency back when something needs tuning. Of course agencies don’t go away since human judgment is always needed, but a growing share of what clients pay for shifts toward skills and agents that run inside the business. I keep coming back to this idea and it keeps making more sense.
