It’s going to cause a massive unemployment surge very soon. I would argue it’s already happening. I work for a big tech company. We are being made redundant. I’m fine with progress, but this is going to singularly change what it means to “work in IT.”
As an aside, keep in mind that the reason the auto industry took off in this country was that Ford made a vehicle that his own employees could afford. The magic of what Ford did was that he didn't just create a product, he simultaneously created a product and the consumer demand for that product. That was the "real" economic magic.
If AI makes products that no one can afford, it will be useless.
That said, perhaps there will come a day when robots become end users (i.e., consumers) and human consumption will no longer drive the economy. But in the mean time, here we are.;-)
