Quantum computers are.
'Quantum computers will surprise the Bitcoin community.'
true, but only half of the bitcoin community. the half that thinks quantum computers mean the end of bitcoin. they will be surprised to see that first we are very far away from it being any danger and then when it became one many years from now they will be surprised as bitcoin will have had upgraded to resistant algorithms!
unfortunately at this point there is a lot of misinformation about quantum computers around that has made a lot of people think they are magical computers that can break anything you want with a press of a button!
