If it's indeed solvable by software then it'll still sell fine, but this is one of the articles I have read where the claim is made that it is a fundamental design issue and cannot safely be fixed. I know nothing about aviation but I do spend a lot of time in planes and I sure as hell won't be boarding a MAX until the fix has been flying around without accident for a few years (I try to fly Airbus only anyway but that's not for safety reasons).
