Why do we still use steam as a primary means of producing electricity?

It’s been more than 200 years since the widespread implementation of the steam engine.

Why is this still the most prevalent means of producing electricity? With things like fusion reactors, why is it so hard to convert the thermal energy into electrical energy?

Steam is used in most fission reactors and unless there is some fundamental discovery it will be used in fusion reactors as well. When something is cheap and efficient why change it?

Imagine 100 or 200 years from now you somehow are still alive and able to think rationally and someone asks you “why are we still using electricity and electronic devices, …?” How might you answer their question? Can you see how you question today is similar?
