> Does any body uses Redux these days?

New projects, hopefully not, but there are untold millions of lines of existing code out there that use Redux, in code bases that will continue to grow their usage of redux.

May I suggest Formik instead of react hook forms. The way it handles internal form state has always seemed more intuitive to me.

What exactly is wrong with redux though?

One change to one item in the global store will fire up subscriptions for every single item in the store. I don't care how fast those comparison checks are thanks to Immutable.js, it's still a big waste of CPU.

Tons of unnecessary code overhead for doing very simple operations.

For simple forms, redux buys you nothing, but it is easily 3x the code.
