That and the impending heat-death of the Universe keep me up at nights, worrying
worrying worrying...
But just when I thought that the human race was going to Hell in a handbasket,
this happily comes along to explain it all...

Doesn't go far enough.
In my youth I heard old men talking about how things were much better
when they were young. Now as a member of that race. I too remember
things were much better when I was young. Going on that premise There
must have been a "Golden age" in the distant past.

CT is the same. From a mile away, they are fine and alert one to their
presence (which cracks me up how people drive to 200 feet and slam on
the brakes "OMG, a cop!").
But, driving through a scene, I can't see shit, like if a cop decides to
walk in front of my car. If there's only one cop, I block the light
with my hand, but if there's multiples, I'm doomed.

And yet, the auto manufacturers claim that the blinding Lexus blue
headlights are no more bright to oncoming traffic.

They have apps that turn off the blue channel so as not to disturb your sleep
cycle. I've been using one for a few years now.
Super easy to set up - set time on , set time off.
Yes, cop cars are insane. Need to endanger thousands of drivers in traffic to
hand out that one stupid ticket.
"Respect my AUTHORITAY!"
Not to mention them talking on cell phones and USING A LAPTOP WHILE DRIVING.

It cannot be otherwise of course: the law of entropy you know :-)
But I agree about the heat death of the universe. That still really is a
worry...

By my calculations, the Golden Age is a linear ever-shifting time period,
exactly 52.3 years before the present time (+/- 4 months.)
The calculations are too complex to post here, unfortunately...

I can see how you got that figure. Without actually doing any of the
calculations, you understand?
If you take 52.3 years as your starting point and recursive it by half.
That tends to 104.6 years which is where we get a discontinuity. Before
which it was the Greeks what dun it.

Surely you mean, too trivial? ;-)

Trivial??!! I used Einstein's field equations for gravity and time dilation.
Naturally!
(Oh... but I forgot to include the cosmological constant, and the correct
'flavor' of quark. That's certainly going to throw my results off. I
apologize...)
