All these optimists want to say it will just "enhance" our abilities, not replace us. Well AI did "enhance" our chess playing skills, but it completely replaced the top skill level. That's ok for a game without economic value by being the best. But with these same people advocating that we can't stop because the potential economic value is so great and economics improves peoples' lives... We will use the replacement AI for economic value, not the inferior "enhanced" chess players.
