Pre-home internet I remember running a line-in to my soundblaster card from a clock radio and recording Tool’s Sober to my HDD.
The wav file took up a good chunk of the HDD. After a good amount of funking around with encoding it was barely comprehensible and still took up too much room. Was exciting and felt like a glimpse of the future.
I have a graduate diploma in economics and concur it’s mostly bullshit. The lecturers essentially agreed. Didn’t bother to continue to masters as I don’t think there’s anything more to learn from the field once you’ve confirmed that the world economy is based on lies and dice rolls.
