You are not storing these things in your head at the expense of anything else. You’re “training” the existing underutilized capacity in your brain for something useful.
Pidgin (and its OTR plugin) used to be the most popular client for OTR (Off-The-Record, an encryption protocol) messaging. That was my experience about 10 years ago and back then I think the plugins were known to be a weak point in its security.
I spoke to a few Alameda/FTX people over drinks before summer. They were delighted to brag about the lack of separation between the two entities. Really there wasn’t any.
Sure we add up the numbers, but there are thresholds for everything anyway. We might not be concerned about something within a 1MM range let alone a floating point inaccuracy. The uncertainty is accounted for already.
I got this too. Even with a strong interest in the business area and multiple hours of interviews going well: “You’d be a great fit here”, “You were technically strong”, … , “We don’t think you really want this job”.
I really wanted that job. That’s only the most recent, but I have had an overwhelming number of these experiences. I know my own worth, but to convince someone to actually let you work for them - impossible.
