When I first got into my hobby (DJ) I thought I only needed to pay into the set up cost of buying equipment (turntables, mixer, sound), but I eventually learned that I had to keep buying records because I couldn’t just mix the same two recorded forever, and that got expensive.
I just recently had a 2020 gen MacBook pro die on me. When I took it to the genius bar, they said that it was a power issue that they couldn’t repair unless they changed the whole logic board which would cost me $500 and without the ability to recover the data on the soldered SSD. What’s worse is that they sent me to a 3rd party data recovery company to recover my data for $1200. I ended up declining the data recovery and just accepted that my data is gone and bought a thinkpad to replace the laptop.
Cool math games.
