The web revolution is to Windows UI what vibe coding is to programming today. It brought in a massive group of people who didn't need to understand message pumps, or handles or non-blocking api calls. On top of that, it delivered incrementally more capable result each year. View source taught millions how to build modals, blurred overlay. Meanwhile, the old group of programmers were still worrying about how to protect the knowhow behind compiled languages.
I agree with the thesis of your post, but where we differ is that I think both of those were (are) bad things. Both web apps and vibe coding are causing the market to be flooded with low quality software, not only making the market worse but also giving future generations fewer examples of well-made software to look up to.
