Tanstack always had one of the best data tables by far. But component libraries as a business model are dead in the water at this point sadly. Your whole product can be replaced with a few minutes of prompting now. Abstract design languages for agents to build around are the future, not concrete implementations.
I agree, but there is still a decent market left. I see new boilerplate launches and making a 5-6 figure revenue. It's not supposed to be a revolutionary startup or anything, but can be a decent side hustle.
