Comments by "Rob Fraser" (@krashd) on "How IBM quietly pushed out 20,000 older workers" video.

IBM had the world's first functioning mouse and thought it just a novelty and put it on a shelf, they also created the first GUI "the cursor and folders" thing every operating system on Earth now relies upon on. They put that on a shelf too because they believed computers would always rely on a keyboard and command line to be operated. IBM eventually realised that they were being slaughtered at the marketplace because all upstart companies were run and populated by upstarts who could tell what was or wasn't going to be fashionable over the next five years, while the majority of their workforce became dinosaurs. Not all elderly employees, but the majority of them. They were late to realise that tech was something you had to have a hard-coded disposition for, not every person will stay at the vanguard of what's new, but young people do that by their very nature. It's not that difficult a concept to grasp if you've ever seen a tech documentary, the same happened in the UK with Sinclair, his young employees wanted to get into the home computer market while he thought every young person would rather own a pocket calculator.
