I am also lazy and I made the fastest (for now) implementation of bsgs for gpu. The difference between us and him is that we let people use our developments and sources, but he does not. If everyone sits in their own world and does not share knowledge, then there will be no progress. And this applies not only to him, but to others as well.
Agree 100%, for example If I hadn't shared my code, the speed of my implementation would be slow as a highly optimized python code for the same purpose.
Jokes aside, those are some of the advantages of the Open source code, it is always getting improved.
