If you're able to predict, you're able to simulate.

> are so evenly matched

It's because the real value of the models is in what we (humanity) fed them, and all of them have eaten the same thing for free.

Well, my business would be paying the trips, and everybody still refuses. So it's not the money.

Let's call it a valid UUIDv0 - all bits randomized including the version bits :)

Not sarcasm. Not cynism. Just pure humor.

I don't do any moral judgement at all, and I also don't predict the future.

I respond to "You are not causing more water to be used by asking a human to work on something.", because that statement is false. (Mental) work has an effect on the human metabolism.

That's certainly not true. Asking me to think hard about something will cause me to burn more calories. Asking me to do physical work even more so.

There are projects where long term addicts are given pure medical heroin (Diamorphin) in a controlled environment, and they do considerably better than their control group who does not receive their drugs like that.

E.g. https://patrida.de/

100%. I don't want to know how the sausage was made. It's similar to research papers, or history books, where the way we arrive at results or outcomes in the real world is often quite different from the way it's presented in the final form.

If you're self hosting your compiler on C, you are your own user.

Maybe I'm missing something, or we do it differently here, but I think "spec" is defined to narrowly in that article. Start writing the first part of that document in that meeting, and everything ties together neatly.

I also discuss on a local newspaper forum as well, which is pretty popular, but the crowd here tends to be more insightful :)

We might be able to bring back some nuclear reactors, but building new one's: that's not on a feasible timeline.

Destructive operations are both tempting to some devs and immensely problematic in that industry for regulatory purposes, so picking a tech that is inherently incapable of destructive operations is alluring, I suppose.

On a meta level, seems this trajectory follows Alan Kay: first we made the complex things possible, now we make simple things simple.

Stockholm (SL Bus/Train via Märsta 47kr vs. Arlanda Express 340 SEK)

Vienna (S-Bahn S7 4.40 EUR vs. City Airport Train 24.90 EUR)

While with the Stockholm one, the public transport option is cheap but a little bit more complicated (there are convenient medium priced options too), the Vienna one is really just branding and a non-obvious exit to the train station.
