I do think quantum is an issue that needs to be monitored and eventually addressed but I also think a lot of the near term hysteria is FUD. I don't understand enough about the scaling capability of QBits but what I do know if powerful quantum computers won't be in the hands of random hackers any time soon. Google or Stanford aren't going to hack bitcoin. The question would be how advanced are foreign actors who might want to hack Bitcoin. Of that I am not really sure. Probably not as far as US based quantum research but maybe far enough that we need to start thinking about it.
