It's slightly taboo, but I think people protect their kids more now because they are more precious to the parents. The average number of children per mother has plunged in the last 200 years, and investment required in them per child to get them to child-bearing capability is much higher also. Child mortality has dropped like a stone, so any harm coming to children is much less tolerable.

Parents have so much invested in their children - and so few of them to "spare" - that they get far more protection than before.

But civilisations have always forgotten things and then had to re-engineer them. We only recently recreated Roman-equivalent concrete; knowledge required to create the Saturn V rockets had to be re-engineered; we can't recreate medieval stained glass exactly, or Viking Ulfberht Swords; we would struggle to create Betamax tape today.

Many of the examples I found (as expected) relate to military or commercially sensitive technology that did not get written down (for obvious reasons).

It also reminded me when I read Thomas Thwaites' "The Toaster Project: Or a Heroic Attempt to Build a Simple Electric Appliance from Scratch", where to make a smelter from scratch he relied on a 450 year old book ("De re metallica" by Georgius Agricola), as well as a friendly Metallurgist.

We already lost the widespread ability to write assembler in an artisinal way. Now we have AI we will also be lazy about how we write individual bits of artisinal code. So what? Yes it will cost more (in time and money) when we need to re-engineer, but how much would it cost to keep alive all the knowledge and skills we might possibly need in the future?

We had better make sure we write down and preserve the recorded data though :)

It's much more structured, with a facilitator to help reduce the possibility of dangerous behaviours. It forced me to confront aspects of myself I otherwise might never have. It also (I think) gave me greater insight into what might be behind people's public faces.

POSIX Korn shell, specifically, according to Wikipedia:

https://en.wikipedia.org/wiki/PowerShell#Grammar

so maybe it inherited 2>&1 from Korn shell, which in turn was POSIX.

But yeah, Powershell was not built purely to be a POSIX shell, but I thought it tried to be compatible where it made sense (hence the seeming clash of cultures).

The TV I have now in my living room is closer to a computer than a television from when I grew up (born 1975) anyway, so the word could mean all sorts of things. I mean, we still call our pocket computers "phones" even though they are mainly used for viewing cats at a distance.

Scrollbars used to be invisible to me. They only bubbled up to my consciousness when I needed them, and then there was no friction in their use. Now I am having to think about them constantly. To me that is 'standing out'.
