Used to be nerds hanging out on IRC, distributing Slackware, hacking trialware, modding games, etc. that had the passion and problem solving determination to do software work, which used to be harder due to lack of access to information.
OTOH what a great time for a budding engineer. I'm in my mid 30s, and no longer have the same stamina and passion as in my teenage/20s, but in the last 5 years I've learnt so many things I could not have done so back in the day. I learnt and experimented way more around random topics like compilers, OS, electronics, databases because of ease of access to information, AI (:shrug:), even though I have way less free time.
