I hear you. Z80 was my first CPU too. I started with a borrowed ZX Spectrum as a kid (family couldn't afford to buy one, but a neighbor had one, and my father could borrow one from work over the weekends from time to time). I quickly got bored of playing games (loaded from a Grundig cassette tape player - that one we owned), learned BASIC (built-in), then assembly, spent some time hacking games (think unlimited lives, or invulnerability hacks, some of mine were even published in a national computing magazine). Eventually saved up enough money to put together my own Z80 based computer but only calculator display and calculator keypad - a lot of fun to play with (yea, I cheated a little, used the borrowed ZX spectrum to write the code for it - also managed to get my computer to load code from audio tapes, copied the ZX Spectrum algorithm with some improvements - mine was faster, higher effective baud rate). Then moved onto 8501(a 6502 relative) as my father managed to acquire a Commodore Plus 4 which was a huge failure for Commodore (primarily because it was not compatible with C64), but because of it we could afford one being liquidated from some store. And on, and on...
But despite our nostalgia for the Z80, I doubt many people of future generations will experience any of it. The vast majority of future computer engineers will never be exposed to much beyond vibe coding. Take a random grad today, ask them to code a game which can run in 16KB RAM (not a typo, actual base model ZX Spectrum RAM size, which could play games), they will look at you with pity - "You meant 16GB, right?". As I write this, Chrome tells me this tab of the browser, containing nothing but your reply and mine, uses ~100MB of RAM, not counting shared based Chrome code of course. ZX Spectrum had 16KB - 48KB or RAM, my Commodore Plus 4 has 128KB of RAM, and they had games, spreadsheets, word processors. Commodore Plus 4 was only able to access 64KB at a time (switching between 2 64KB banks - most of the software never used even the additional 64KB at all).
