I think compared to 15 years ago there's (1) more capital (2) more founders [enabled by better tooling and well-known implementation patterns] (3) less low hanging fruit on the product side. Any given opportunity is more likely to have other, well-resourced, folks chasing it hard.

I think this is the biggest factor that actually affects the fundamentals of selling tech. To my eye, every other aspect is some form of Gordon Gecko business insanity and/or VC people looking to stoke egos by making people with good ideas feel like big shot executives while figuring out how soon they can throw it all in a juicer and extract a bunch of cash.
