Echoing others here, but I think part of it is that a lot of the new tech is designed to make things worse.

If I think about new tech, all the examples that immediately spring to mind are negative ones: surveillance cameras, AI-enabled spam & propaganda, autonomous weaponry.

The less flashy advances tend to be harder to get excited about, and they're also often negative. My computers get more expensive, but they also collect more data on me, and it's harder to get one without a bunch of unwanted features.

People used to be excited about new tech because it was exciting and aspirational; I think we've lost a lot of that.
