In the industry I work in, I've seen such miniaturization that it amazes me. When I first completed tech school years ago it was neet seeing vacuum tubes phased out. Transistors, then SMD's and chips that blended pre-amplifier circuits, oscillator circuits, etc, etc. to the point where the only thing not on the single chip was the final amplifier and that only because the heat that was involved. As circuits become smaller they also work far more efficiently and thus less heat as well. The radio gear I use in amateur radio can't be created by us guys/gals any more, just too much pre-fab'ed equipment and circuits. The 2 meter and 440mhz walkie talkie I use in my car fits in the palm (literally the palm not including fingers) of my hand, and has a complete telephone for phone patching, memory storage for hundreds of frequencys to be stored with offsets for transmit/receive, special sub audible tones for activating other radio's or activating repeaters, etc. At work CCTV cameras now fit onto the size of a nickle and can transmit wirelessly for several feet, again limited by power. Looking back it amazes me....but just beginning to venture into AI I am amazed all over again. Thanks for the great and stimulating chats, gang!
