For your points:

- Garden path approaches are definitely a thing, but I don't think this is necessarily catastrophic. A lot depends on the language and framework in question, and also the driver of the change.

- I think it's that plus the fact it's easy to just generate ever more code. Solutions scale in every dimension until they hit a limit where it's not feasible to go further. If AI tools will allow you to write a project with a million or 10 million lines of code, you can bet it will eventually happen. Who's ever gonna fix that?
