Web is where the new stuff
was happening. The browser is very constrained - most of the 'new' stuff is to get around the browser shortcomings - e.g. react, angular. These are to solve front end problems that have been long solved on desktop environments (.Net, Delphi, VB maybe even Obj C though I'm not a fan)
Actual new tech is in the mobile sphere now imho, or server side AI, very little of this is web development except for the occasional front end for said apps.
