I'm a data scientist and not a graphics programmer, but my guess is that it's just abstracted away more. If you're using ML/DL libraries, you're mostly just calling APIs that handle the linear algebra and calculus for you. Unless you're actively contributing to those libraries, you likely don't ever need to "touch" any of the underlying operations. Up to a point, it's useful to understand how things work under the hood, but where that point is kinda depends on your job. For instance, I could write code to do 'naive' matrix multiplication, but I couldn't, like, contribute to BLAS.

My wife works at the Fed, and I can confirm that 1) the Fed does decommission/retire bills and 2) that whole process is very tightly controlled. The retired bills are typically shredded, and if you go on a tour of a Fed bank, you can get little baggies of "Fed Shreds."

So it seems very likely to me that whatever money is in the cube is decommissioned.

I used to work as a barista, and we had several entrepreneurs/small business owners who worked at the shop regularly. Most were friendly with one another. I'm not sure if any actually did business together, but they definitely chatted here and there.
