> We've gone from a sense of techno optimism to tech blaming.

IMO this is simply because the tech industry isn't what it was 20+ years ago. We didn't have the monopolistic mammoths we have today, such ruthless focus on profiteering, or key figures so disconnected from the layperson.

People hated on Microsoft and they were taken to court for practices that nowadays seem to be commonplace with any of the other big tech companies. A future where everyone has a personal computer was exciting and seemed strictly beneficial; but with time these "futures" the tech industry wants us to imagine have just gotten either less credible, or more dystopic.

A future where everyone is on Facebook for example sounds dystopic, knowing the power that lays on personal data collection, the company's track record, or just what the product actually gives us: an endless feed of low-quality content. Even things that don't seem dystopic like VR seem kinda unnecessary when compared to the very tanginble benefit the personal computer or the internet brought about.

There are more tangible reasons to not be optimistic nowadays.
