It's the smallest number bigger than 0.

That's a coincidence of the particular number system you use, and many programming languages have multiple number implementations.

Racket starts with arbitrary precision rationals.

You must go up to something like limits to make ... meaningful.

Professor N.J. Wildberger is probably among the most well known "ultrafinitist" on YouTube.

I mention him because I would think he sympathizes with those who have concern over the meaning of this kind of notation.

> A stateful function with effects. Your language just doesn’t have a primitive to express it.

I wonder what about generator functions?

I find it somewhat comical that the governor of Maryland had his wife pull South Korean connections to buy masks. So terribly ad hoc.

So should black people stop organizing along lines of race, because that doesn't seem like an effective way to fight racism? That just means less black representation.

Plenty of people are hurt or killed through clerical errors by medical professionals, but you're not going to get anyone admitting that. Even for something simple, if you have any accusation to make in a medical context, it's probably time to evaluate your options and consider a new doctor, and only then make your accusation.

I think tech moved too quickly and in some ways, due to power being left on the table by government, tech became responsible; much like how businesses have taken up the responsibility of American healthcare due to the issue being under-addressed by government.

Now that YouTube is used by people of all ages, Google has to make social and political decisions about what kind of content is appropriate for different ages.

I'm talking about whether anecdotes of safe dogs is an argument that we might need different levels of licensing. Yes it's an argument, especially in the face of empiricism on the community burden of cats.

Of course it’s an argument because we can simply license based on predictors of burden. Small dogs which are projected to fall below a risk tolerance threshold should have less licensing burden.

Similarly, different classes of vehicles get different licensing requirements; saying all cars are the same is just lazy, and a regulation meant for big risky entities being applied to small ones is what we call regulation moats. We have enough pet owners that we should be able to quantify risks and burdens for the purpose of licensing. Here we have an article which provides empiricism on the community burden from cats.

IMO what’s important isn’t merely whether something poses proximal danger to human life (which asks for immediate and more severe solutions), but whether something poses greater community burden on a level where it’s hard to trust an individual to self regulate.

Owning any equipment or process with bad waste or ecological burden should also require extra licensing under the same rationale.

That's a bit different. I can fake swipe-up on a GUI but I can't fake Ctrl-Alt-Del.
