You mean Waymo, not Tesla there, but they absolutely do yell at you to close it if you leave one open for even a minute or so. I know because we used one and got yelled at, though we were just unloading stuff at the time and closed it afterward.

> If your debt is denominated in dollars how does depreciation in the dollar make it harder to pay back?

It doesn't, it just leaves the general public holding sacks of worthless paper money or pointless numbers in a bank's database when they want actual stuff, like food.

Inflation as long been used as a stealthy way to tax the public, they see their quality of life going to crap as each new generation comes along, but nobody wants to admit the problem lies with government spending The US had the advantage of pushing a lot of the inflation tax onto the rest of the world, but that's going away as so many other countries want to get free of the dollar.

If tomorrow the government hands out a trillion dollars to everyone, we won't all suddenly have a lot more stuff. We'll have a lot more paper and all the resources that were scarce yesterday will still be just as scarce. Probably even more so as there's a rush to consume more before prices can fully react to such a change.

> We have been hearing these same predictions about the national debt for almost 100 years ... the argument is fundamentally flawed. Mostly because it ignores things like economic growth, inflation and the value created by whatever the debt buys.

The fiat system has collapsed a few times, do you know anything about Brazil or Zimbabwe?

I don't think gold is a magic solution here, or returning to that standard would fix everything, but you do need some level of balance between the amount of currency and the things there are to buy with it and we damn near broke it during Covid with the mass inflation there. So I wouldn't be too cavalier that this could never happen, even as I don't think it's in any immediate danger.

But remember: there won't be a US dollar to peg the US dollar to if we screw it up and that's the only way Brazil got out of its mess in the 1990s.

Meanwhile, you can get $100 trillion Zimbabwe dollars for $3 USD.

Yeah, because the customers don't want anything else. Itch.io is great ... if you want random indie stuff. GOG seems to have no idea what to recommend and you either get games from 1992 or hentai VNs with a porn patch so they're not technically selling the porn, with little that's actually interesting.

A good chance? Lol.

A *vanishingly small chance*. It's not approved as a primary textbook anywhere. It's not in the APUSH book list. Etc.

You'll find a few teachers that use it as a primary text, and a few more that use it as a supplementary source. I would wager that the latter group is well under 1%.

We might be hitting noise floors near physical limits, but there's plenty of room for innovation -- interfaces, processing, integration, etc. But little incentive for this to happen with so much concentration in the marketplace.

If you want a 12-ENOB 2.5GSPS DAC, you're paying hundreds of dollars; this isn't *extremely* high end, either. Prices haven't really been falling on the high end for several years.

They don't make any "high-spec" SKUs and it would be quite a lift for them to try to enter this market; they top out at 1 *MSPS* don't they? There's a lot of black magic to make it work.

First, we're down in the weeds down here. I replied to someone who said "SF median teacher salaries are between 100k and 150k" and "and that doesn’t even account for benefits", providing a source that shows mid-career teachers make $98k on average *including benefits*. So that was pretty much fail.

> And this doesn’t change the easily verified overall fact that the median teacher salary in virtually every state exceeds the states’ overall median salary

Given that all of the teachers have above-median education, it would be rather extraordinary if this *weren't* true.

On the other hand, teachers have above-median levels of education, too.

> and that doesn’t even account for benefits,

Actually, your source does account for benefits. It says mid-career teachers in San Francisco Unified make $98k in total compensation counting benefits. And, of course, mid-career is not median; a whole lot of teachers wash out of the profession early.

Comment Statistical irony (Score 1) 337

The irony here is -- on a properly designed exam the median student should be getting a 50-60 raw point score out of 100. This is what gives you the greatest statistical power to distinguish student performance. Then, a "C" at 41/100 is not unreasonable and entering it as 0.30 + sqrt(score) * 0.70 in the gradebook makes a lot of sense.

But this doesn't mean taking existing exams where students show mastery at 85-95% and then accepting 41% as a C.
