AI will impact productivity but not replace humans. We have the needs and wants, AI lends our goals, it has none of its own. We'll expand our desires to match the increased abilities and remain as busy as always. We can't even begin to imagine the future applications, and that's where most of the work will be.

The ability to train huge models does not belong to a single entity and many of these models get shared with everyone. So you can right now type "import transformers" and have thousands of trained models at your fingertips. All these toys are ours (thanks to important work done for free by some of us) we just need imagination to use them.
