You can generally tell when the true operational cost, including cost of capital, significantly exceeds employee cost by looking at whether they pay people to work in the middle of the night.

There are quite a lot of places where that happens. Just using the OP's list:

Airplanes: there are fewer flights at night, but that's when a lot of required maintenance happens. The Internet tells me the average lease on a Boeing 737 is around a few hundred thousand USD per month. Bigger planes would have even bigger differentials with their crew salaries.

Machinists: there's a reason you picked this example. Really expensive machine tools can run into the multiple millions though, plus maintenance and consumables. Lease rates can easily go into double digit thousands per month. And that's not even considering exotic stuff. Lots of high end shops operate around the clock.

Radiologists: Most of the operating costs for big medical imaging equipment are going to exceed the employee operating it, though maybe not the radiologist. Getting a radiologist to work outside regular business (or banking) hours is a chore, but the techs do so routinely. Sometimes the actual operation is the expensive bit so no night shifts, like anything involving a SQUID.

Tower cranes: don't work as much at night probably due to safety, but lease rates mostly in the double digit thousands a month and up.

Trading analysts: Bloomberg terminals are a few tens of thousands per year, so no. Some of the crazy HFT stuff probably does cost ridiculous amounts though, so maybe the quants writing algorithms for it rather than the traders.

Garbage men: maybe. Probably yes if you count the salary of one guy, no if two.

Concrete truck drivers: probably. Also probably semi trucks.

MWh is a unit of capacity

The word you're looking for is "energy."

"Capacity" can have pretty much any units depending on what you're talking about. Generation capacity, for example, is usually measured in Watts. It's common to talk about battery capacity in terms of power because if it can't provide enough power it's no good at all, and then time; i.e. make it work, then make it good.

The Internet tells me that California is a mythical place invented to tempt children into windowless vans and teenagers into dressing in black and giving money to poor people. Just like the Internet told me the things the GP said.

I don't think "continuous" means what you think it means. The reason you can do this is because the models are continuous.

"JaiLIP" is just running gradient descent on the input until you get the effect on the output you want. The same thing works just fine on our brains except it's less efficient because we can't (yet) differentiate over our output. We call them "optical illusions" even though they don't have anything to do with actual optics.

What are letters? Books are just splotches of dark ink on light paper.

we could get Congress

This is what the OP was talking about. YOU, collectively as the voters, are in charge. You've been brainwashed very deliberately to think you're not, but also yay USA democracy freedom bestest fuk ya, and then that learned helplessness has been used to exploit some foundational weaknesses in your system.

and the average citizen

You have also been deliberately made dumber by being convinced education is bad and should be expensive, and wedged and distracted by irrelevant garbage.

"The government you elect is the government you deserve." By none other than your own Thomas Jefferson.

Both ways!

Sure they want updated engines. That dosen't mean that, lacking new engines, they don't want the planes they have. Not having any A380s at all would be a pretty big problem for most of the airlines that fly it.

The A350 1000, or the 777x, have a little more than half the capacity of an A380. That's twice as many flights.

The uses for bitcoin seem to mostly decrease as it becomes more popular. It's great for sending money around without paying taxes or getting the attention that taking a briefcase full of bills through the airport gets... until bitcoin gets popular enough that governments recognize it as a briefcase full of cash.

In hindsight, it's fairly obvious. When you get tired of arguing with your employees what do you do? Hire someone else to do it for you. Then when you get tired of arguing with them, you hire another layer to do it for you. Et cetera.

That's the magic of the loop. The agent tells you it's doing everything perfectly.

Ah, given the social skills and anger issues you must be a console gamer. See, when your computer isn't in a fancy box with "Sony" written on it you can put any downloaded file you like on any medium you wish. You can lend it to a friend, once you've downloaded it you don't need any "storefronts" at all, etc.

Your inability to copy files off your computer sounds like it's a problem all right, but I'm not sure that problem is Rockstar.

Hey, come on. When cracks were found in the MD-11 engine mount on several aircraft, Boeing looked into it, concluded a failure "would not result in a safety of flight condition," so there's no need for replacement but you might want to eyeball it every five years or so. The FAA was cool with it and everything was totally fine. Totally fine.

Okay, one engine fell off on one aircraft, but that was actually due to something else and it definitely wouldn't ever happen again.

The A380 is already out of production. The airlines that fly A380s really want more though. "Not economical" depends very much on what types of routes you fly and how much landing and takeoff slots cost at the airports you service.

Might be the other way around. Notion was neat variation on the note taker app. Add a floating chatbot button you can't get rid of, some nagging to try their meeting transcription, collaboration features, connect your calendar, an e-mail client apparently, hey, why not integrate your crypto wallet and a social network and a payment platform and.... Of course to support all that you have to hire more developers, who need to be paid, so more ads or higher subscription fees.
