There are only two ways to make money in business: One is to bundle; the other is to unbundle. So the idea behind unbundling of Airbnb is simple: Pick a niche use case with passionate but unsatisfied guests and then build a business around it.

A few months ago, Smith wrote an AI-skeptical article where he threw some sentences at the GPT-3, a text processor from Open AI. As wikipedia puts it:
When good ideas make bad business
Working in tech, I've observed developers who work as hard as possible when they don't need to. I’m here today to tell you that it's a bad idea and you shouldn't do it.
In my last Oxide-related post I got Oxide’s Propolis software running and said I might try and get their sled agent up and running next. Anyways that didn’t happen. Instead I ended up reading datasheets, writing rust codegen, spending 16 gigs of ram for an hour to build docs for a crate that’s just a glorified bundle…
