Learned about superheterodyne receivers. Recently I've been studying up on RF technology, happened to come across superheterodyne receivers a short while ago, decided to research them today, saw that Technology Connections had a video on them, watched it, and felt reasonably enlightened.

Are there AI enabled antennas by now?

I don't know about AI antennas, but smart antennas[1] are a things since more than 15 years. Basically they are array of antennas that can change via software the directivity (mainly used in radar systems) or increase/reduce power transmission and direction (this is used in 5G cell).
