alt Hacker News> It's generally speaking part of the problem with the entire "XML as a savior" mindset of that earlier era and a big reason of why we left them
Generally speaking I feel like this is true for a lot of stuff in programming circles, XML included.
New technology appears, some people play around with it. Others come up with using it for something else. Give it some time, and eventually people start putting it everywhere. Soon "X is not for Y" blogposts appear, and usage finally starts to decrease as people rediscover "use the right tool for the right problem". Wait yet some more time, and a new technology appears, and the same cycle begins again.
Seen it with so many things by now that I think "we'll" (the software community) forever be stuck in this cycle and the only way to win is to explicitly jump out of the cycle and watch it from afar, pick up the pieces that actually make sense to continue using and ignore the rest.

There have been many such cycles, but the XML hysteria of the 00s is the worst I can think of. It lasted a long time and the square peg XML was shoved into so many round holes.
A controversial opinion, but JSON is that too. Not as bad as XML was (̶t̶h̶e̶r̶e̶'̶s̶ ̶n̶o̶ ̶"̶J̶S̶L̶T̶"̶)̶, but wasting cycles to manifest structured data in an unstructured textual format has massive overhead on the source and destination sides. It only took off because "JavaScript everywhere" was taking off — performance be damned. Protobufs and other binary formats already existed, but JSON was appealing because it's easily inspectable (it's plaintext) and easy to use — `JSON.stringify` and `JSON.parse` were already there.
We eventually said, "what if we made databases based on JSON" and then came MongoDB. Worse performance than a relational database, but who cares! It's JSON! People have mostly moved away from document databases, but that's because they realized it was a bad idea for the majority of usecases.
