Makes sense to validate businesses as early and cheaply as possible.

While AI accelerates initial product development, there might be a tail end of costs, like tech debt that plagues a product for years. For startups that die, it won't matter, and startups that "make it" (in VC terms, i.e. jackpots) can afford to rebuild the whole product from scratch.

These will be more product concepts than new-tech. I've worked for a couple of companies that needed tech to support features but focused on just having features. Customers would have loved the products if the features worked well enough. Let's see how these ones work out.
