I reject the core assertion that there was a "lost decade" at all. I was deep in the frontend industry during that time, and many "use the platform" purists completely missed the reality of what people were building with better abstractions: much more complicated and ambitious frontend apps. These apps heavily used new browser APIs and features, they just did a lot of it in frameworks like React, which these purists despised. I think the era we're in right now is fundamentally different.
