The main difference for me between 2002 and 2012 was how smartphones let you be online all the time, and everything that comes with that. I distinctly remember being lost in a city with a friend around that time. We had to call someone we thought would be near a computer to MapQuest directions for us. By 2012, basically no one would have that experience. (I actually got my first personal smartphone in 2013, but my SO had had one for a couple years at by that point.) The quality of resources for just about anything available online jumped quite a bit during that time, too. In high school, going to a large library was still useful for some school projects. By the time I was done with college, you could at least do a first pass at gathering information on any subject online. Video on the internet was terrible in 2002, but YouTube was very much a thing by 2012, as were other ways to stream TV and Movies. I think desktops for general home use phased out in those years, with laptops and later phones and tablets becoming the primary device format for consumption, and leaving desktops for work and gamers. In 2002 technology was still largely for kids (who learned about it in school) and nerds (who have always liked tech). By 2012, your Grandma had an iPad. As kind of a final note on that period, there was a line in an early episode of The Wire that's something along the lines of "What are you going to do with a computer?" That line would have fallen completely flat by 2012.

2012 to 2022 has seemed to me to be more of a period of refinement. Connection speeds, wi-fi availability, etc. have all improved drastically. Devices are thinner, and sometime feel higher quality. Basically, a lot of the same trends from 2002 to 2012 have continued, but there hasn't been a paradigm shift like there was in the early 2000s with the finishing up of the trend from the late 1990s of getting computing devices and internet connections into homes, and then getting most people online everywhere via mobile. If anything, I guess the biggest change 2012 to 2022 has been the advancements in safety technology in cars, with lane keeping, automatic braking, and so on.
