In his more formative years, my dad was a radar man in the Navy. It’s interesting to consider that with today’s modern technology, I would suspect that just about everything he did back then has since been completely overhauled, deprecated, and otherwise rendered obsolete. Radar, as we know it, is no longer a viable way of detecting precise movements that a military unit requests.
It’s interesting then to take a step back and ponder what other technical formats have since been made obsolete during our own times. Surely, we would feel very out of place in this day and age if we suddenly found ourselves in a position where we have to use a payphone. Remember card catalogs? It’s hard to believe these were still the standard 25 years ago as I was going through grade school.
