At what point is qqqm better than voo for young investors?

Anytime qqq is mentioned to have beaten voo the past 15-20 years people say “past performance does not guarantee future returns” but they use that same logic for VOO when they say its averaged 10 percent for many decades.

If someone is young why not add in alot of qqq alongside with voo? After all, the companies are investing a shit ton of money in AI so why not jump on the train? I really dont think most of these brick and motor companies like home depot, target are gonna be around vast majority of things will be delivered by drones or in other efficient ways.

The economy is no longer about mcdonalds and coca cola its about tech and AI
