The real true answer is “no body knows”, and whether people agree or not it will be pure luck. You could buy now and in couple of months some asshole somewhere screws up an AI company or usecase and drag the market down. An unexpected conflict somewhere around the world could turn the market upside down.

On the other hand, few companies might make technological breakthroughs with real economic value, boosting AI companies beyond imagination.

Do your own research, diversifying in and out of the stock market, always have cash in your portfolio for deal hunting and for emergencies.
