It's a grift for funding. We still can't factor all 5-bit numbers (the largest was 15-ish, but even that wasn't general IIRC) on QCs. Scammy startups are out

It's a grift for funding. We still can't factor all 5-bit numbers (the largest was 15-ish, but even that wasn't general IIRC) on QCs. Scammy startups are out there claiming all sorts of non-sense; ask them how many bits (arbitrary) they can run Shor's algorithm on and all their hyperbolic claims fall flat. Shor's alg. is still the gold-standard when it comes to QC's definitive advantages on Classical machines (all the ML ones have been disproved IIRC). All of the words in the above sentence are important, because they'll weasel out and cheat if you don't include them (even Google/IBM do this).
