That's super interesting, I do remember being taught as a kid how to use Google Image search (circa 2005), Gimp for photo manipulation around the age of 12 in 2008, we had technology classes with electronics, technical drawing, even some plastic bending machine, and light programming (made a robot figurine execute recorded moves in sequence)

I do wonder if it's still the case in my own country

To be fair, the overwhelming majority of people regardless of age don't know what LaTeX or markdown are. Not the best examples. I'm a millennial with a 4 year STEM degree and I maybe used LaTeX once because it was required, and before Discord became a thing, I'd never heard of markdown. Most people who use Discord probably don't even know it supports markdown.
