If I can recreate your "frontier" SaaS with day-to-day coding, it has no value. Or perhaps the few months' lead was never the deciding factor.

the vast majority of successful SaaS offer capabilities or services no where near the frontier.

furthermore i'd argue that the success of an saas, or really any startup, has more to do with things aside from the code and service itself.

Finance management, social connections and effects, word of mouth, networking -- probably all more important than whether or not the todo app uses a functional language and is formally proven.

What the hell are you yammering about. Everything in the economy exists at different quality/price tradeoffs, everything from tomato sauce at the grocery store to landscaping services to SaaS. "Compete at the frontier" is some maximalist buzzword nonsense. Do you think Ikea is crying because their furniture is cheap and they're not "competing at the frontier"?

Sounds like you suffer from Dunning-Kruger. AI is making a lot of dumb people look smart. A lot of us can see right through it.
