I just realized that modern web applications are a group form of procrastination. Procrastination is a complex thing. But essentially, it's putting something off because of some perceived pain, even though the thing may be important or even inevitable, and eventually the procrastination leads to negative outcomes.

Web applications were created because people were averse to creating native applications, for fear of the pain involved with creating and distributing native applications. They were so averse to this perceived pain that they've done incredibly complex, even bizarre things, just so they don't have to leave the web browser. WebSockets are one of those things: taking a stateless client-server protocol (HTTP) and literally forcing it to turn into an entirely new protocol (WebSockets) just so people could continue to do things in a web browser that would have been easy in a native application (bidirectional stateful sockets, aka a tcp connection).

I suppose this is a normal human thing. Like how we created cars to essentially have a horseless buggy. Then we created paved roads to make that work easier. Then we built cities around paved roads to keep using the cars. Then we built air-scrubbers into the cars and changed the fuel formula when we realized we were poisoning everyone. Then we built electric cars (again!) to try to keep using the cars without all the internal combustion issues. Then we built self-driving cars because it would be easier than expanding regional or national public transportation.

We keep doing the easy thing, to avoid the thing we know we should be doing. And avoiding it just becomes a bigger pain in the ass.
