I don't expect to live long enough to see the completion of searching up through exponent 108.5 or the 100Mdigit threshold, unless there's a huge paradigm shift. Moore's law is running out. https://www.mersenneforum.org/showpo...5&postcount=11 Maybe quantum computing will change things enough, someday/year/decade.
There comes an exponent level whose PRP or LL test is incalculable by conventional means because there's not enough mass in the known universe to store the full interim residues on, even at 10 bits/subatomic particle. And most of that hypothetical memory's mass is very far from other parts of it, implying VERY low clock rates and iteration rates.
