> Is “unagentic engineer” a euphemism for human/not-AI?
Pretty sure it means someone who plods along in life, going with the flow, working but with no self-conceived roadmap of ambition, low extroversion, low desire to make decisions, etc
Perhaps it be better to consider 3.5 years as a half-life instead.
Every 42 months, half your life has or could be upturned.
That’s how long it takes to find yourself in new job, or for a new child to become a fully talking toddler with a personality, or a long-term relationship to solidify, or a national government to turn over, or a pandemic to initialize and then resolve. That all tracks.

It cannot be used by TSA employees. They are not allowed to even wear dosimeters.
Those big backscatter X-ray machines [1] have a powerful X-Ray tube. Not that I'd be worried if I flew once a month, but if I was a member of the aircrew and going through more than once a day I'd be concerned. Think about when you get a medical or dental X-Ray and the operator puts on a lead apron and goes around a corner -- they don't get anywhere near the dose that you get, but they are around the machine all the time time. TSA staff did none of that.
Those machines were killed off because it was easy to demonstrate walking right through them and not getting detected if you wear a gun in a holster the way you would normally wear a gun if you weren't trying to hide it. The trouble is it depends on the gun being between you and the scanner because the gun appears black against the white radiation bouncing back from all the hydrogen atoms in you. With no background the gun is black-on-black and invisible. When people realized you could put a cop in front of the scanner and demo that the scanner couldn't see his gun it got around quickly that the scanner was worthless. [2]
I'm not sure what is the context of your link. Is it supposed to show that TSA employees are not permitted to wear dosimeters? Because if so, I can't find that in there.
In case of Earth, Wikipedia describes [1] it as being "[..] generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in Earth's outer core". This makes Earth a geodynamo [2]. (The aforementioned Wikipedia page is actually really long and detailed, a lot more than I would have thought)
It's actually driving north south that changes the rotation speed. Because your 'real' speed gets higher as you get closer to the equator, you 'steal' momentum from the earth as you get closer to the equator.
Its effectively the same principle as a figure skater pulling in their arms when spinning, to spin faster.
Reminds me of a glorious question from undergraduate physics:
Calculate the change in the length of the Earth's day if the UK were to switch to vehicles driving on the right-hand side of the road rather than the left..
It was indeed all about the roundabouts. I forget the details but I do know it took us quite a while to get there(!)
Those tutorials filled me with dread at the time, but with hindsight they were - how can I put this - a fairly formative experience.
Watching your tutor use paper and pencil - and estimation - to calculate something like that was actually quite inspiring. That was, once it stopped being terrifying.
