To those that need a simple explanation about the artificial intelligence bubble: The AI bubble is companies pouring millions into the technology without having any idea what it will do for them. The reason it is being compared to the dot-com bubble is that companies also invested in anything to do with the internet without having any idea what it would do for them or how it would be profitable.
Some companies will make out like bandits and be worth billions; most companies will be worth the noodles stuck to the wall. Companies are throwing millions(billions?) of dollars at anything AI-related to see what sticks and hoping it pays off.
