YouTube just suggested this video from 1953 to me: Given that I was born in 1949, I was about 4 years old when transistors became a thing. In my late childhood, an object of lust was a transistor radio - the more transistors the better! I had one very similar to this one - and many others over the years. How far we’ve come. I had to look it up, but the processor in an iPhone 12 has 11.8 billion transistors! I wonder if those Bell Labs scientists had any idea what they were setting in motion.
