”After the completion of the 7-man, some people were curious about the feasibility of building the 8-man. Ronald de Man estimated that without modifying much the generator, the task requires computers with 64 TB RAM and 2000 TB hard disks[10] (cost about $640K and $40K respectively in 2020). The generator can be modified to work on much cheaper computers with 64 GB RAM but that may need a few thousand years of computing”
And to solve chess you’d need to calculate the 32-piece tablebases.
