I tend to not really care for most new things, as most of it feels cheap, inauthentic or a scam to further the surviellance facist oligarchy state. Id be completely content with time frozen in 2004.
So, to be a little more positive, what are some new things that are actually good?
I think that the TinyTapeout concept is super cool (https://tinytapeout.com/). In the past, it was not really feasible to design and manufacture a semiconductor device as a hobbyist... Unless maybe an extremely wealthy one.
Now, we have open source design tools, open process design kit, and the ability but small part of a manufactured wafer.
There are also now multi-project wafer runs for photonic chips at reasonable prices for startup/academia. I think these developments are pretty cool.
