What surprises me is how little technological progress appears to have occurred in the last decade (ie. 2010-2020). I think you'd be hard pressed to name a decade in the past 50 or even 100 years where the technology available to the masses has advanced so little. Note that I'm excluding things that are still mostly at the research stage, like deep learning, advanced language models, etc., since I don't think those have had much effect on people's lives yet.
