Everything is relative, @Aquamarina1234. I don't have sufficient technical knowledge to land a man on the moon by myself and the vast majority of what I know was self-taught, but I was given a good start in technology at school and had the good fortune to fall into a job in medical technology where I had to either sink or swim. I swam; and as I swam more, I realised it would become necessary for me to learn the breast stoke and butterfly stoke as well as the front crawl. I had a thoroughly engaging career that began in electronics, moved into mechanical engineering and in the latter years of my career in technology ended up with explaining technology to punters who wanted to buy machinery they hoped would make their dreams come true. I owe my career to my school teachers. The one who influenced my early career the most, thought little of my technical ability, but I took in what he had to say and when the need to refer to it occurred, I was most of the way there. Having witnessed over many years how technology teaching has declined, I fear for our future. My days of pushing back the frontiers of technology are over, but wouldn't it be great if there was a younger generation I could pass the baton to and get them up to speed on what I'd worked out, so they could take it further. I have no idea why, but school leaders think kids are better off flipping burgers and stacking supermarket shelves than they would be imagining the part they might play in the future of technology. It's unbelievably depressing.
