The number of circuits that one can make from, say, thirty 4-pin parts
probably exceeds the number of electrons in the universe. A human
brain can explore an incredibly large possibility space that no
procedural computer program could ever approach.

But LT Spice is great for evaluating and evolving ideas. It
complements the more creative but less quantitative brain. I sometimes
design by fiddling in Spice, letting it check the reasonableness of my
instincts.

I have a couple of recent designs that evolved in LT Spice and work
great, that I still don't understand.

On the contrary computers excel at assessing far more designs than we can because they're fast & tireless. We can rule out most options very quickly so we don't need to spend time assessing them. Which is faster? Depends on what's being assessed and how.

Conventional computers are horribly slow. They can't even drive a car
safely.

Brains are probably quantum computers that can simultaneously
superimpose enormousely large possibility sets and collapse the good
ones.

Spice sims of random circuits won't design anything useful, but harvest the unused cycles of half the PCs on the internet and it becomes at least possible. Maybe in 50 years we'll all be obsolete.

There have been attempts to design with computers, or to do the easier

That is to say if you only tell the algorithm to use "minimum number of
gates" and don't enforce a rule that they must all be powered in some
way it will sometimes find a minimum gate solution regardless that
works, on one particular device, for one particular task. "Life finds a way"

Indeed, but neural nets do not work that way, although you can emulate it somehow in a procedural way.
In the beginning it is about non-linear weights between elements where data is stored in those weights
(variables if you will).
The learning process changes those weights but the hardware complexity stays the same
while getting ever better 'answers'.
(This put right? I did some neural net programming years ago,
things have evolved enormous after that).

Our brains only uses a very small subset of its neurons for 'design'.

But LT Spice is great for evaluating and evolving ideas. It
complements the more creative but less quantitative brain. I sometimes
design by fiddling in Spice, letting it check the reasonableness of my
instincts.

Yes, but I still like to understand what I am doing
OTOH how much in depth _do_ we understand, we do no even know everything about the electron and even less about the universe.
So from that realization we will always be tinkering.
The steam engine that started the industrial revolution was also the result of just tinkering ..
AI can do that without getting tired around the clock...

I like LTspice for filters etc, but there are many good filter design programs on the web.

Also I do think much in blocks that I have ever designed and build and chips I have used.
Also more and more is becoming software.

AI designing software???

Now that could create fun solutions.

If you'd want a design that translates to all devices you'd have to run
your genetic algorithm at a higher level of abstraction that only
simulates the aspects of the FPGA you want it to be able to leverage.

Algorithms like that I think are still not any good at doing full
systems but can definitely be helpful at optimizing sections. The
mixed-Chinese postal route problem has applicability to electrical and
systems engineering and GAs seem to do better solving it than previous
human-devised solutions:

Yes, and neural nets have very different solutions to that sort of problems.
A while back a postman was arrested because he never delivered the post,
they found thousands of letters and stuff in his house after many people complained
about not getting important mail.

Just a few months before that an other postman was caught burying hundreds of letters
in the woods.
It made the routing a lot easier for them I think.

Somehow a brain does massive processing and memory and image
recognition in fractions of a second, using millisecond logic elements
and wet chemistry. It couldn't go that with an array of equivalent
logic gates. Nobody has a clue how that works.

I was takling to a neighbor, at our annual block party. He says that
he can't remember names or numbers very well, but he never forgets a
face that he has once seen, even briefly, decades ago.

Bats echolocate with equivalent ear-to-ear timing resolution in the
nanoseconds. Whales and porposes see the shapes of moving objects with
their sonar.

Well nobody has ever built a logic array where each element is connected
to 500 others.

I've heard claims that the brain uses quantum events to pick options,
and the randomness gives the appearance of free will.

But if that's even possible at 98.6 F then why do quantum computers need
liquid helium?

or 10,000 others, which is closer to the fan-out I've heard quoted.

I've heard claims that the brain uses quantum events to pick options,

Actual freedom is not necessary anyhow, except to a philosopher. Any
behaviour which cannot be distinguished from randomness is sufficient to
support the (unnecessary) hypothesis of free will.

Given the exponential rate of error magnification in a chaotic system,
even the gravitational pull of a single electron at the far end of the
observable universe can be the "butterfly in Brazil", so it hardly helps
to even talk about "true" randomness in defence of free will.

Even if the randomness is "true" doesn't make decisions *meaningful"...
rather the opposite in fact. The whole philosophical pursuit of quantum
randomness as an exercise in defending "meaningfulness" is pointless and
counter-productive. It only means something to someone wedded to a
Cartesian system where meaning comes across from another realm.

Bats echolocate with equivalent ear-to-ear timing resolution in the
nanoseconds.

Cite? Bats can hear up to 80kHz - where the period is 12.5usec.

The speed of sound in air is 343 metres per second, so the wavelength is 4.3 mm.

Nanosecond time resolution translates to a 0.343 micron spatial resolution, and bat labs aren't set up to measure distances anything like that precisely. Neither are bats.

The signals are subject to a mechanical fourier transform and amplitude
detection in the ear mechanics before there is even a neural impulse to
worry about. Detection of relative phase can then be done at much lower
rates, likely by neural correlators on counter-flowing delay lines. All
very feasible in wetware without invoking majick.

No neural nets are cargo-cult cartoons of a biological nervous system.

Not a bit like a neuron. Even single-cell organisms, with no nervous
system, have complex behavior. Things with a couple dozen neurons have
extremely complex behavior.

NNs are popular in academia for some reason. I've had job applicants,
recent grads, show me their NN projects, which they didn't actually
understand.

I do a lot of math at the whiteboard, in my head, which impresses
people, but it's analog computing, like a slide rule. 10% or
thereabouts accuracy is good enough at a whiteboard, exact results in
many cases.

There have been "human computers" who can do high-precision
numerical-digits math in their heads.

What is funny is the sort of lame excuse at the end:
"It's tempting to think that this AI will replace engineers, but that's simply not true," said McComb. "


It is totally obvious at least to me that a more complex neural net can do more.

This is going to be bigger and bigger..

This is also why I an sceptical of too much math and things like El Tea Spies,
I design differently.

The number of circuits that one can make from, say, thirty 4-pin parts
probably exceeds the number of electrons in the universe. A human
brain can explore an incredibly large possibility space that no
procedural computer program could ever approach.

On the contrary computers excel at assessing far more designs than we can because they're fast & tireless. We can rule out most options very quickly so we don't need to spend time assessing them. Which is faster? Depends on what's being assessed and how.

Conventional computers are horribly slow.

You jest. An early 70s pocket calculator could do maths faster than we can.

But it can't design anything. It can't play table tennis.

your claim was that computers are slow. Even the most primtive CPU IC wasn't. You've got to go back to the Harwell Witch era to get slow.

They can't even drive a car
safely.

Nor can humans


Brains are probably quantum computers that can simultaneously
superimpose enormousely large possibility sets and collapse the good
ones.

we don't know

Somehow a brain does massive processing and memory and image
recognition in fractions of a second, using millisecond logic elements

logic gates. Nobody has a clue how that works.

their sonar.



But LT Spice is great for evaluating and evolving ideas. It
complements the more creative but less quantitative brain. I sometimes
design by fiddling in Spice, letting it check the reasonableness of my
instincts.

I have a couple of recent designs that evolved in LT Spice and work
great, that I still don't understand.

Spice sims of random circuits won't design anything useful, but harvest the unused cycles of half the PCs on the internet and it becomes at least possible. Maybe in 50 years we'll all be obsolete.


NT

There have been attempts to design with computers, or to do the easier
task, optimize a given circuit. Not much progress so far.

Sure, a lot more compute power is needed. That will be available & cheap one day.

Maybe not. Some problems don't get solved much better by applying more
and faster Intel CPUs.

But obviously coming up with lots of random or otherwise circuits & assessing them does.
