Yeah absolutely the owners of them will (and already are) reaping the rewards. Bill Gates has suggested we need a "robot tax" to pay for a UBI. By whatever mechanism, we need to increase taxes on the rentier class and the new "productivity rentier class"*, and get that money into the hands of consumers if we want to stop capitalism from collapsing in a screaming heap.

* A term I just invented to describe those automaters who benefit massively from productivity gains through automation, while the wages they pay to their dwindling human workforces barely increase at all.
