I was pondering today that while laser guns and flying cars were predicted for the future, they haven’t come to pass. Video phone calls only finally became popular because of the pandemic and also because of the one thing no one that I am aware of, predicted: that we would be walking around with far more computing power than a 1975 supercomputer in our smart phone. More memory, more cpu, faster cpu, just being used to do graphics, photography, games and the like rather than run scientific FORTRAN IV :)

So, no flying car but a supercomputer in your pocket. An interesting tradeoff…
