I guess I’m easy to please, but, recently I got myself a better bluetooth dongle over the holidays. I had one before, but it was stupid cheap, connection was frail and didn’t have good range. Now I have one with Bluetooth 5.4 and I’m amazed with what I can do with it.
I can funnel sound to any one of my bluetooth speakers so I don’t have it hogging my main speakers when I want something close by me.
Speaking of which, I wish I had really known this far earlier in my days of using a computer. But, being able to split audio in multiple ways. I can assign where sound is going to, program to program. One browser gets these headsets, that browser gets the TV speakers .etc
That kind of shit amazes me and damn shame I never explored this before.
Not technology in general, but there are specific technologies that are mind-blowing.
Back when I was in college, IBM announced they developed the technology to manipulate individual atoms. They used it to spell out “IBM” at the atomic level.
Not sure where or if they ever DID anything with it, but that was fascinating!

They progressed to animations
This was in 1981, crazy
