What were the key insights or surprises you got from that 13,000 word piece?
For background, I contributed to Anki long ago, wrote regularly about SRS in the late 2000s and got deeply into them for language learning for a few years. Later, I mostly stopped using them since I found extensive reading both more interesting and a better return on my time.
True, as much as I enjoy owning and controlling my own hardware, buying an A100 and then letting it sit idle while I procrastinate and play video games probably isn't the best use of resources. He did say "my GPU" (or similar) at one point, and I thought maybe he does enough ML stuff that he bought his own.
