I've had the same experience of looking up and finding an old answer from someone I knew, but one that I made _myself_ for the exact same problem I've just hit again years later... :D
I’ve had a worse experience - I end up looking for a solution to a problem only to find an unanswered question from years earlier, which was also asked by me back then :(
If I had an dollar for searching and finding a reddit thread that I created for a question that I eventually had to find the answer to myself since somehow everyone else remembers this, I'd have at least 10 dollars.
