By definition, a black swan event cannot be predicted. It doesn't just mean "a larger fire" or "the event of a lifetime".

Your examples are cases in which you know what the bill is going to be before placing your order. With LLMs, you're paying per output token, not per request, yet you don't get all the tokens.

When you hire lawyers or consultants you usually don’t know how many hours they’ll bill you. It will depend on developments in the case that you cannot in general predict. For example if the other side files a motion and your lawyer has to argue against it, they’ll bill you for it.

Sure you can set spending limits, just like you can make an account and give it a limited amount of credits.

They offer both a subscription model and a lifetime purchase. Or that used to be the case, at least. But I agree that it feels like it's getting behind.

How do they compare with Faber Castell 9000? (I normally write with these, in HB or 2B hardness)

The Blackwing Matte is close to a FC 9000 6B.

In softness I guess? Because I wouldn't consider any of the "B" series really matte :)

How are laptop GPUs these days in terms of energy consumption? My last experience was a while ago, but the battery drained fast with them active.

They still eat battery, but at least the midrange ones, not nearly as much as they used to.

I only know the Uni system of a few European countries, but generally I would expect Philosophy to be a prerequirement that you take for your entrance examinations, not during studies per se (unless you're studying humanities, of course).

Taking propranolol in this case is, in fact, an example of being a functioning adult, and a solution that also works for oral examinations.
