When did integrated circuits first enter your life?
digsys:
Somewhere around '66-67, my neighbor had a fully equipped ham radio shed, he worked / designed for Radio Rentals I think. I learned a lot from him. Nearly everything was valves with a few transistors thrown in. We had one of these "modern" weller soldering irons - Wasn't too bad on transistors, because you could bend each lead - then one day, a transmitter radio came in with an 8pin IC - something like an LM741. WTF was it ?? Anyway it was dead. So, ran the Weller round and round the pins trying to remove it - flooded them with solder - everything. One side would always cool down too quick. Tried a small screw-driver to pry it off - NOTHING !! Possibly 15-20 mins on it !
Then I made my most famous statement ... funny how vividly I still recall it ... " I don't know what these fookers are, but they'll NEVER EVER take off !!! Ahh memories

An IC first entered my life in the late 60s, when I stepped on an early upturned DIL package.

Your first encounter with semiconductors was with a silicon part? How very modern. All the cool people worked their way up to silicon through copper oxide rectifiers and germanium transistors. :)

Yeah I’m not over half way to 100 yet :-DD
To be fair I spent a good amount of time in my early years playing with valve radios. Way before I got my hands on a transistor.

Then surely your first encounter with semiconductors was copper oxide rectifiers. They were very common in later valve radios.
