Gen Z walks into a room with just USB-C and calls it a day, while millennials and older devs still have PTSD from the connector wars. You needed a PhD in port identification just to hook up a printer back in the day—Centronics Parallel 36pin? DB-25 Serial? FireWire 800/3200? Pick your poison. But here's the kicker: we traded the chaos of 30+ different physical connectors for the absolute minefield of USB-C doing everything and nothing at the same time. That innocent-looking port could be USB 2.0 (480 Mbps), USB 3.2 Gen 2x2 (20 Gbps), Thunderbolt 4 (40 Gbps), delivering 15W or 100W of power, or just... decorative. You literally can't tell by looking at it. At least with PS/2 you KNEW it was for your keyboard. Now you're playing Russian roulette with identical ports wondering why your "USB-C" cable won't charge your laptop or transfer files faster than dial-up. Progress!
