Exactly. I'm a retired coder, a good one, so I do it for fun mostly when I have time and interest, and it becomes boring after a month of managing a network of GPUs.
I have a question, if this is just for fun, why do you keep the knowledge to yourself? I understand that we mortals keep things to ourselves to have an advantage, but how does that benefit you? And you will say that you shared kang1 but your "SOTA" code I have tested and implemented on GPU and it is even slower because it makes excessive use of ECC operations, while the ideal is to work with Int and only use points where strictly necessary.
so even though you think you are a good programmer you prove the opposite, which makes you even more suspicious of being the creator and you went crazy, staining your own lore.
C'mon, everyone knows "State Of The Art" code needs a proprietary compiler and a proprietary OS, and zero explanations on what it's doing. My very first post on this forum was about the level of arrogance of some users, we're at the peak now. I write low-level C code for 20 years, have a few certificates and can pass with 100 score any programming quiz in two dozen programming languages, and I can understand and optimize stuff at the assembler level, but I would never qualify myself as a "good coder" not even after I will retire, because there is something new to learn every day.
I don't think we'll ever see RetiredCoder's crazy fast GPU kernel with cycle handling and so on. He either used other methods, or like to burn money (and our self esteem at the same time).
