Probebly because media articels are not representative of most of what happens. And the difference between a job at a Musk company and at comparable job in a different company is far smaller then it is claimed.
One of the big problems with JavaScript is that some developers don't know it very well (me included) but have to get some feature working, so import multiple frameworks/libraries to get their job done, most of which is not needed.
Why would anyone want to work in places like this?
