Exactly. I got my first computer as a kid in 1981 (a Casio PB100). The manual was excellent, and I learned BASIC as well as some numerical analysis with it : Monte-Carlo method, systems of equations, etc. My parents were short of money at the time, had a large house, and took guests who needed a place to stay for a few months. I remember long discussions with a couple of computer specialists (as we said at the time) working for major banks. They only seemed to know VM and COBOL on big iron computers, punched cards, line editors on ttys, and files on tapes, so, "serious" computers which have practically disappeared except in legacy applications. They made fun of me with my small device and my dreams of having an Apple ][ or an IBM PC, which was worth the price of a hot hatch at the time, and that my parents could not afford, saying that a real computer was worth minimum $1M, or how I was using a TI 994/A at school to play some music. I realized they had almost no concept of a backdoor, and were hardly gasping the concept of a superuser, which I knew only from books, but had understood. Now, I am using the most powerful computers of the planet in atomic energy centers, and still think of them making fun of me trying to program 2-degree equations or 3-unknown linear equations on my 512 byte computer in BASIC. They did not seem to see the point, since they only thought about (non-relational) databases and accounting.
