>I’ve seen startups trying to innovate in this space for many years now, and it’s surprising that absolutely nothing has changed.

I don't want to be too crass, but I'm not surprised people who can startup a business are precisely the ones who hyper-fixate on efficiency when hiring and try to find the best coders. Instead of the best engineers. When you need to put your money where you mouth is, many will squirm back to "what works".
