Businesses presumably sell things. If AIs get good enough to run a business autonomously then what are they selling that I can't just use AI to make myself?

Does the AI actually do everything, or just act as the CEO?

It'll ultimately take a lot of time to produce a polished product that people actually want to use. We're seeing that clearly. The vibe-code-an-app-this-weekend capability is producing almost exclusively a giant pile of worthless garbage, rather than an explosion of apps that humans want to use. It's mostly someone in a garage welding two pieces of metal together for the first time, and then roaming the neighborhood in celebration: look, look at what I have done, look, two becomes one, I have done this, look, amazing, I could probably build an airplane or a generator.

The bar will be raised + it'll turn out to require a lot more time & effort than is currently thought to produce something of good quality (even with Fable 6 et al). The smaller utility programs are easy for AI to turn out.
