QC solves one kind of problems, that are hard for classical computers, but not another (see all the links to post-quantum crypto in the comments). OTOH there will be a very large window during which QC will be cheap enough to rent by the hour on AWS, but equipping every lightbulb with a QC will be prohibitively expensive (think current GPU prices).
