It's easy to shoot yourself in the foot with any technology. People switch to a technology thinking they're writing better code with it, but in reality they're just a better at coding. Or it's a rewrite of something, in that case you know more about the problem you're solving. If you're bad at coding jQuery, when you switch to Vue or React, you then have gigantic mono components, if else if else rendering, 5000 state variables, or some other thing that you shoot yourself with.
