I started programming in 2015 and I'm very surprised that webapps have managed to get worse in that time period. We have 10 years of work on the V8, 10 years of React and Angular, 10 years of DX improvements and my current work is C# takes a minute to compile and Angular takes 4 minutes for a production build.
I know now we have TS and there's a lot of safety that comes with it but somehow things are just slow, both building and on deployed websites. Websites should be snappy when everyone has a GPU that can go incredibly fast compared to 10 years ago and cores that are 2x faster and 4x as numerous.
