Why are quantum computers (going to be) important?

I made a post in an old thread about how Quantum Computers differ. For context, the thread was asking whether Quantum Computers would aid in computing fractals more quickly:

The value in quantum computers is that it opens up an avenue to solve different sorts of problems we can currently only solve on a very small scale because our current computers need to simulate a quantum computer’s thought process to solve them*.

  • NB: we don’t usually solve these problems by literally writing a QC simulator, we usually use some parallel algorithm that just so happens to explore all the possibility branches a QC would naturally explore via quantum state.
