Good. I'm glad they got here. I mean mathematically there's
usually no distinction of time's arrow. In most of quantum
mechanics you can go forwards or backwards willy-nilly as the
equations suit you. This leads to all sorts of wonky theories
about the Universe. Great for Sci-Fi imagination-provoking
theoretical physics, but terrible for building real machines
that do real stuff. Hoping further confirmations of Entropy will
allow them to built machines that are effective at the subatomic
level, getting them past the engineering difficulties of
machines built at such small sizes, and give them some
reasonable timelines for repair and maintenance of subatomic
machines. I mean we can spend all day talking parallel
Universes, Universes without cause and other fun weird stuff,
but at the end of the day, we as a species want more interesting
stuff. More technology. Better computers that can do more things
more efficiently. Awesome stuff. Can't keep our head in the
clouds all the time and say, "Oh, the Universe is mathematics
and balanced and pure" and stuff. I want a device that does
stuff. Give me a device that can repair broken stuff in my body.
Strengthen my memory. Paint that acts as a touch display
computer so I can type on my tabletop instead of needing a
computer/phone/tablet/whatever. [computer paint is my weird idea
- been wanting that for years, even before smart phones were a
'thing' - ever since I saw the Apple Newton "Tandy Zoomer" back
in the early 1990s, predecessor of the smartphone/tablet]
There's a lot of great tech possible once we stop getting
religious about quantum mechanics. Studies like this confirming
entropy nails down the reality of the nature of things a little
better and can let us get to making stuff. 'cause I like cool
toys.
