As an old time computer nerd I have uncountable examples of deprecated knowledge. There is no use in knowing how to use the reserved upper memory in autoexec.bat and config.sys, nor how to use Napster or Kazaa.

But all these skills do shape your brain and way of thinking.

Assembly language taught me to be precise and think before typing. Flash taught me that nothing lasts forever, as big as it might seem.

Eventually, all this adds up and creates a profile that is very demanded in my career.

That said, my mom taught me to thread a needle without looking. And I can’t sew, so that’s that.
