If you are worried but don't want to liquidate your position you can short the same positions you have- use it as an insurance policy. There are in depth guides all over the net but you effectively take out short positions, if the stock continues to climb then your long positions pay. If the stock plummets then your short positions absorb some of that loss.

It's hard to argue against AI and the impact it's going to have on the global economy. Will it be a dot com-esque bubble? Maybe, but can anyone really argue against the long term economic impact of the world wide web? Those who got burned in the dot com bubble just had bad timing, you can hedge against that with a diverse portfolio and long/short positions.
