I always feel uncomfortable when someone speaks for someone else who has been dead for 50 years but ...
Walt Disney seemed to enjoy technology. I suspect he might have embraced technological advances.
Socially, each person reacts to change differently and, had he magically lived to be 110 years old, I don't think it's possible to say one way or another how Walt's views would have evolved over the last 50 years.
It's unrealistic to take someone's mindset from years ago and instantly transport it to another time. We do not live in isolation; we are products of our times. In order to know what each of us would be like today, it's necessary for us to have experienced the events that led up to today, and each of us reacts in different and sometimes surprising ways.
Walt is no different and we have no way of knowing how events of the last 50 years might have shaped Walt's thinking.
I will leave you with a few Walt Disney quotes to consider:
"Get a good idea and stay with it. Dog it and work at it until it's done, and done right."
"I function better when things are going badly than when they're as smooth as whipped cream."
"Disneyland is a work of love. We didn't go into Disneyland just with the idea of making money."
"I could never convince the financiers that Disneyland was feasible, because dreams offer too little collateral."
