I'm skeptical of the idea that work can be consistently decomposed in such a way that an outsider can be effective immediately on anything other than toy problems. Saying "they can point their agent at it" is handwavy.. it helps but any mature codebase is still going to take weeks to get up to speed on, and there's going to be gaps that an agent can't fill because the knowledge isn't in the codebase. This seems like it would only work for mostly green-field projects that don't require a lot of expertise. Even things like "how do I use the product" can take a couple days to get up to speed on.

I also think this is pretty bad for candidates. The last thing I want to do is a bunch of unstable gig work for fickle startups in one of the most expensive places to live in the world. Also, I really think this only works if you decouple things like health insurance from employment, otherwise the instability can be too much for a lot of people.
