There is one big wrinkle in existing firms trying to adopt the kind of near-full AI business automation mentioned here: internal people and groups will strongly resist it as it's an existential threat to their interests. See what happened at Meta as an example. To bypass this, the company would pretty much have to run a parallel AI org alongside their main human one, but at that point they are almost on even footing with startups in a lot of ways, as anything the AI org builds is orthogonal to the existing human business. And you probably won't have a competent and extremely motivated founder spearheading it all.
