I'm in my 40s and therefore generally in the "get off my lawn, kids" age.
But I totally agree with that article. I've converted quite a few legacy devices with barrel jack to USB-C - and got rid of a huge box of junky old power bricks. Especially for devices I only use occasionally I don't want to search for the matching power bricks - I just want to plug it into one of the 4 USB-C PD sockets I have installed into my desk.
