nothing stops you from simulating load. something that scales, by definition, it will have something in the small that is more or less identical to something in the large. it goes both ways.

the obstacle was always the parade of tedious obstacles to create (in this case) a sophisticated virtual harness to simulate (in this case) whatever the hell this article is about. so yeah, actually, the capability of retail coding plans are kind of the only thing that matters...

This is the SaaS advantage you can still have in an AI era. You can beat your competition by being exposed to more of the real world than them. For example, anyone can vibe code an accounting app, but no matter how good AIs get no vibe-coded AI app can have a track record of what happens in an complaince audit and whether it stood up during a tax audit from some particular jurisdiction. The real world will always be more complicated than an AI can vibe code a solution to, if for no other reason that as we advance in AI, the amount of stuff an AI needs to deal with is going to increase from everyone else doing AI stuff too.
