Tangential, but there are so many common in-use technologies we should be in awe of but aren't. I mean, just look at the average home or apartment built relatively recently. For example, we have reached standards of insulation, weather-proofing, and energy efficiency that would just blow the mind of any builder from just 30 years ago (not that there isn't room for improvement). It's not flying cars or robot butlers, but it impresses me at least.
