It seems clear that bots will dominate humans in many/most competitive closed-world games over the next couple of years:

They are already unbeatable in perfect-information games like Chess and Go. They could crush human motor racers tomorrow.

They will be unbeatable in games with limited information (Dota/Starcraft) within months.

The next frontier is donkey-space games like rps, poker and day-trading (https://universalpaperclips.gamepedia.com/Donkey_Space) where they are already beating pros. It may be another couple of years before they totally dominate here.

FWIW I think I'd reverse the order of poker and StarCraft -- I think Poker's already beating world champion pros regularly, but last year's SC2 champ (Serral) doesn't think it's at his level yet, which is corroborated by its MMR being lower than his on ladder. And DeepMind seem to be winding down their SC2 involvement now, without issuing a challenge to him.

What I really meant was...well..things other than gaming (come on HN, think big). Why make music if AI started making the "best" music?

Whoever is currently making music is also (statistically) not making best music. Maybe not even good music. AI doesn't change anything there.

Plenty of people give up on plenty of pursuits because they realize that they can't innovate or the whatever their "top" is.

Plenty of other people don't care and continue to do what's new to them (and what often turns out to be new to others.)
