Coal consumption in the US peaked in 2007 but there is still a shit load
of it shipped about.

On weekday overnights on this rail cam in Kearney, Nebraska you can
watch 200 car unit coal trains run by maybe about every 45 minutes on
average, all night long.

Don't you love the insinuation that the semiconductor industry is
going to save the coal mining industry as we move away from using
coal as fuel? That's hilarious.

With the right teacher sure, anybody can learn to code
it is no different from making a route in a map:
go left, turn right etc..
It could actually be a big improvement over current bloat makers...
Just start with 'hello I am a coal miner" in binary on some micro.
Even simpler: Ask AI to write it.
Difference between cooking your own food and going to a Mc Donuts.

But the fun with coding is that you also need to learn about what you are coding for,
so a never ending adventure,
BASIC may also be a good starting point, for example
haw to calculate how much more a coder makes than a coal miner.
that may well motivate the students.

Using a a grapheme layer a couple of carbon atoms thick in your
electronics isn't going to use much coal.

It's certainly true that burning coal wastes a very useful chemical
resource, but using coal as a chemical feed stock isn't likely to make
enough money to keep more than one mine open. The fine chemical business
can be lucrative but it isn't all that big.

In the 1920s, or thenabouts, the science of eugenics established that even a complete certifiable imbecile can be trained to perform complex tasks.

John Larkin doesn't seem to be either smart or beautiful, except perhaps
in his own estimation.

"Haploid human genomes, which are contained in germ cells (the egg and
sperm gamete cells created in the meiosis phase of sexual reproduction
before fertilization) consist of 3,054,815,472 DNA base pairs (if X
chromosome is used).

While there are significant differences among the genomes of human
individuals (on the order of 0.1% due to single-nucleotide variants and
0.6% when considering indels), these are considerably smaller than the differences between humans and their closest living relatives, the
bonobos and chimpanzees (~1.1% fixed single-nucleotide variants[6] and
4% when including indels)."

This still leave room for lot of variation between human beings. Only
identical twins (and triplets and quads etc) start off with identical
genenomes and development builds in variations in methylaltion.

You are very unlikely to see two identical genomes anywhere except in
identical twins. Eight billions individual falls way short of exhausting
all the possible permutations.

if it were true the world would be a better place.

Some people just don't get the first concept: I type words and then
later a machine executes those words to process data.

And a lot of people don't understand data. That's fine, those people

This reminds me of electricians. There are some great electricians,
artists with wire and conduit, who don't understand electricity.

The machine executes the operation selected by that word. If you program
in assembler there's pretty much a one-to-correspondence between words
and operations. In higher level languages this is rare.

And a lot of people don't understand data. That's fine, those people

Touting poorly designed electronic as "insanely good" does seem to be
one of them.

Closer to home, John Larkin imagines that he designs his electronics,
when he merely cobbles stuff together. He never talks about discarding
an inadequate design and starting over.

You post nonstop insults, not to just me but to almost everyone. You
must be a miserable person to be doing this constantly. A slave to
your baser passions without rational control. OK, that's pretty
normal.

But you accidentally bring up an important subject: what IS electronic
design, and what's the best way to do it? (You don't seem to do it, so
this is a question for the people in the group who do.)

Short answer, cobbling. When presented with a problem or an
opportunity to design electronics, the most efficient way to do that
is to grab a piece of paper and immediately sketch a circuit or an
assembly. Sometimes one can do that instantly, without thinking, or
sometimes one can ignore the issue for a few days and then the design
pops up. Sometimes brainstorming and whiteboarding help. Sometimes
fiddling with Spice helps.

All that literature research and math analysis and simulation and
breadboarding and prototyping are just slow and expensive follow-up
chores for people who don't have 100% confidence in their instincts.
Analysis, sometimes prudent to do, but not design.

Design is subconsious and instinctive. And it's free! And to some
extent, it can be taught, but seldom is.

Most of us design things to sell, so do whatever works. We're selling
stuff, not publishing papers.
