My first ever was Stripe CTF in 2012 I think, I still wear the shirt I got (now super fainted) from passing some challenges. I was a student in portugal and remember receiving the shirt for it and thinking, maybe those Americans aren't any better than me and I can compete at the same level.

I never got super into security but it gave me the confidence to play in the same field and lose the stupid aura I had that somehow "rich americans" would be better than me at everything because they had better universities or because of Hollywood or something.

Sad that another cool thing is lost to AI but I guess kids will learn in other ways.
