Delphi lapping the web has less to do with delphi and more to do with the web. Web development sucks and all the frameworks and javascript engines and css preprocessors are just plaster and paint over that fundamentally broken structure.
I do wonder what would happen if modern adaptive development practices ("agile") were coupled with older high productivity dev platforms like Delphi. I suspect it'd be a good combination.
Disagree -- the web platform itself is pretty solid. Websites made decades ago are still accessible. The tooling that exists today will probably last much shorter.
Right. Apart from Flash, Java applets, and the old MS alternative. Those websites aren't accessible in practice, the technologies they're based on are dead or dying.
CSS preprocessors is something I don't want to get into (ex web dev jack of trades 5 legged pony): install gulp, node, npm, git pull, etc. just to build/compile a stylesheet ? Erk. So now I have to work around CSS hacks and the processing quirks, etc. /ranting
