But in the case of New York’s proposed self-checkout discount, the problem is that the bill would actually make grocery stores fire human cashiers in favor of more self-checkout. Imagine that instead of 10%, you made a law forcing grocery stores to give a 90% discount for self-checkout. So everyone would go use the self-checkout machines, and stores would have no need for human cashiers at all. This is kind of like if you told grocery stores to charge 10% more for Skippy peanut butter than for Jif peanut butter. But in the end, patience, education, and reason can overcome accidental slopulism — and AI may help a lot.
