Yeah, now you have a worse problem. A few people like the first chapter you posted, now "oh shit I'd better come up with something good".

A curse on the OP. I was trying so hard to stop thinking about this today.

There have been some experiments with prefabricated construction, but you still run into the issue that shipping really big things is hard, as we've seen with wind turbine blades. Robotic construction might make a dent at some point, but it still seems to be basically embryonic.

You see, the effect on social media on socialization has two parts. The first is the direct effect on an individual caused by their own use of social media. The second is the effect on an individual's social environment when everyone around them is on social media. The first effect is difficult but basically feasible to study. The second effect is downright wicked. So dismissing evidence that hints at the second effect as being "mere correlation that disappears under scrutiny" is not valid reasoning when your process of scrutiny focuses on the first effect.

In social science you have to accept reasoning from incomplete data. You won't always have the answers. I don't think Haidt really stands above or below his peers in any category except notoriety. Of course anyone who has worked with scientists knows to be a little suspicious of a researcher who seems to enjoy being in the public eye. But as the public eye, we're still stuck with them.

It is not a natural assumption that someone will digitize the artwork and use it to adjust a couple thousand matrix coefficients in a complex computer program. To most people that seems like copying with extra steps. The brain may in some ways resemble a computer, but what sets it apart is that we have always lived with brains. Everything a human does has already anticipated the presence of other brains, while etched circuits on ultrapure silicon crystals are something new.

None of the private equity chains with the sans-serif fonts, simplified logos and trisyllabic names are doing this, though. It's bad marketing. Patients don't want to walk outside to an MRI machine in the parking lot. It feels sketchy. Never mind that they score just as well on the ACR image quality tests as the in-room machines. Who the hell knows what that is?

In reality, it's the county hospitals and big universities that use them! Places that have in-house physicists who can argue for what really makes sense in practice. A major problem with healthcare as a business is that the customer does not usually understand the product, but they still need to buy it, and there are time constraints.

The sources you've linked discuss mostly the recovery of additional metals on top of what we have already recovered. That's a different and much harder problem. It's worth remembering that historically, the amount of metal obtained was much smaller — the vast majority of the copper that has ever been mined was mined in the last century, even though humans have been using copper for thousands of years. But historically, that copper was mostly used for consumer products, while today it becomes electrical cables, so it's less obvious how much copper we all use. There's surely enough copper in the walls of my apartment for everyone living here to cook in a copper pan, even though we think of copper pans as being too expensive nowadays.

The problem with modern architecture, in my opinion, is its preference for "dramatic effect": long contours, flat surfaces, high contrast. This is visually exhausting. It looks nice in a catalog and from a large distance, but it's uncomfortable to be close to. This doesn't follow from the use of more glass. It's a historical coincidence that the float glass process made windows cheaper around the same time that architects started experimenting with smoothness.

You're equating life skills to professional skills. I was not taught to milk a cow, but my milk comes from someone who was. The topic is whether software engineers in a professional context learned certain things about software.
