Will there ever be a world chess champion under the age of 10?

Yes, there almost certainly is someone under age 10 today who will be the world champion some day.

Who was WCW at the age of 22?

Carlsen ?

According to Wikipedia that record is now at 18 years of age by Ruslan Ponomariov: "In 2002 he beat his fellow countryman Vassily Ivanchuk in the final of the FIDE World Chess Championship 2002 by a score of 4½-2½ to become FIDE World Champion at the age of 18, the first teenager and youngest person to do so."

NO ONE SHALL BEAT PONO!!!!

mabye yes maybe no

well im over 10 already so.....

Someone can become Nuke Chess Champion or Bulldog Chess Champion or Capture the Flag Chess Champion. That is doable.

By Murphy's Law, that will happen.

Will happen when chess engines are eligible.

we will see they first gm under 10 in 10 years

By Murphy's Law, a world champion can be as young as 5. As 3. As 2. But there is a limit, which means they need to play enough tournaments to show themselves. The average course of a player reaching 2800 now means 20+ years. 200 million years from now, chess tournaments could occur instantaneously, such as by hologram. Scientists may have figured out a way to put a chess database of some kind into the baby's brain. So a baby in his first 2 weeks plays in 20 tournaments instantaneously, by hologram. He plays a Candidates tournament which takes another two weeks. So by four weeks, he challenges the champion. The match will take three weeks. So the conclusion is: The youngest a Chess World Champion can be is 1 1/3 months.
