re: something to cure your lactose intolerance, have you considered transfecting deer lactase genes into the surface tissue cells of your gastrointestinal tract? It worked for this guy, "Am I still lactose tolerant? - Lactose Gene Therapy Update"

As to the main thrust of the article, modern computer tech is rubbish. It all started with the emergence of smartphones with limited energy and networking becoming the dominant computer type. But modern technology is amazing. As for the 5G thing, well, that's an exception. Only 15-20% increases in throughput hertz for hertz were possible form 4G to 5G. Nothing like the 300% increase from 3G to 4G. The low hanging fruit has been picked and all that is left is optimization and using new, not so good, spectrum.
