The number of libraries is too high, but the bigger issue is the speed at which each one is replaced. I thought the ruby ecosystem was bad 10 years ago, and the python ecosystem bad 5 years ago, but these are like sloths on Vicodin compared to the absurd rate at which the JS community seems to adopt and deprecate libraries and frameworks and whatever else they're calling them today.

The worst thing is, every single thing these frameworks are trying to address are solved problems, and have been for decades. But people love reinventing wheels.
