In an attempt to grossly simplify it enough...
AI companies will soon need to start charging actual money for their services.
This is because literal trillions of dollars have been invested into it beforehand, so they need to make a return on investment somehow.
This will then cause big tech corpos (such as Apple, Google, Microsoft etc) to no longer want to use AI, considering that they generally like not wasting money on things they don't need to make money, and AI isn't exactly useful to people using their products.
Therefore, due to lack of demand, the AI bubble will finally collapse and humanity can finally focus on doing more important things.
