This is people having fun with a new technology that is far from perfect, is full of unknowns, but is ripe for exploration and discovery.
Gas Town itself is a piece of speculative fiction: throwing out a hypothesis as to what might be possible were inference to drastically drop in price. Its supervisor + isolated worker + merge factory approach is an experimental spike into how agentic coding could play out at scale.
And funnily enough, it is also the approach that Anysphere arrived at through their own experimentation.
Karpathy's alien technology metaphor is particularly apt. No one knows how to use these tools properly yet. We're having some success and a lot of fun, but really we're only going to find out by experimenting in public and sharing our results. Which means the positive and negative.
They're saying "this is a very thoughtful way to approach orchestration for using AI coding agents". This experiment is profound not because it works or because its THE end game, but rather it's a novel approach worth testing...but so is Ralph AI.
