That NeoLiberal shift did not take place in a vacuum. It was a product of the world around it. It absolutely was caused by tech.
If we — those with the power to build the productivity creators — took a stand and said "we refuse to create tech for the interests of the few" it would have never happened. But, instead, we welcomed it and are responsible for it.
The corollary of “if we took a stand” is that Capital took a stand and collectively undid a lot of the gains of the post-WWII social democratic order.
So no. It wasn’t caused by tech beyond the uninteresting factors like modern society being complex and, of course, that tech developments influence things (pretty much all things).
