that’s scary how dementia works :'(

Sorry 'bout that

I guess there are two kinds of magic. There is the magic of Fourrier which is lossy with funny math. But it is understandable that one can get higher compression ratios when it’s lossy. But I find it even more magic that we can still find better ways to encode images losslessly. I would have thought we had already long found the optimal way

Compression algorithms are magic. Especially lossless compression.
