I could try and explain 'energy return on energy invested' (EROEI) but what's the point? it won't make any difference.
For the same reason there were no solar panels prior to 1800, there was not an excess of societal energy to invent and produce them. Solar panels are not trees.
And relying on trees is not a great idea either, look at Easter Island, lol.
(GPT has all the answers anyway, no need to ask me, I'm an old man with no issue and no stake in this stuff)
And the average increase in world population is about 1% per year, plus the bulk of the existing population is 'developing' i.e industrialization.
As fast as solar, wind, etc electricity production grows, the number of people requiring it grows along-side.
Also, 'renewable' is misleading, 'replaceable' is more accurate, all renewable energy generators wear out as everything does and need to be replaced using non-renewable energy mostly (you can't build solar panels from solar panel energy)
It's interesting that in terms of practical implementations, since each multiply can be done as a series of bit-shifts and additions, and since each element of an FFT is just the solution of a polynomial (a series of multiply-accumulates), in theory it's theoretically possible to do a full FFT in a single cpu clock cycle, much as it's possible to do a single multiply or multiply-accumulate in a single clock cycle (via parallel shift-accumulate operations). It would take a ridiculous number of transistors to implement though.
The world population grows by 200,000 extra people, every day. Keep in mind any adaptations have to compensate for this growth in population, continually, for at least the next couple of decades.
It's worse than that, even just plain oxygen causes cancer (via oxidative stress). It also causes aging at the cellular level.

Not breathing may have more immediate side-effects though.
"Standing on the shoulders of giants" and all that, this goes _way_ back.
Lol, a couple of years go, grown men were getting into fist-fights over toilet paper and it's looking like they are about to wage war over a tank of juice.

Fossil fuels were always worth way more than people ever realized.
Like Joni says, "you don't know what you've got till it's gone."
The hash is merely a convenience, the _actual_ public key used in transactions is present in the ledger and available to anybody who wants it.
Me too, and I'm now grateful to have been proven wrong.
But then again I certainly wouldn't want to be the youth of today and expect the same outcome.
Cerebras have special techniques to work around etching errors / bad cores on their wafers. This is possible since their wafers are effectively hundreds of identical copies of redundant cores. Can't do that for a globally unique model.
Etching failure in that situation would be like brain-damage in a human, all sorts of weird effects would start appearing.
Reminds me of when November 2019 came and went (the date that Blade Runner is set in)
Make hay while the sun shines.
I think so, specifically lossy compression though.
A modern version of the book would include an extra section in the 'Lossy compression' chapter - 'Text' (alongside Images/Video/Audio) that would discuss LLM's.
LLM's seem to be the weird interesting outcome of applying lossy (de)compression concepts to text instead of the audio/image/video domains where they have traditionally been used.
Strange that they are feeding raw audio in. Even in humans, there is a hardware transform to the frequency domain (the cochlea) before data is fed to the brain, effectively doing this part in the LLM seems inefficient.
I had to read that twice, I first thought you meant 4 GB of _storage_...
Worrying about only having 4GB of RAM.... that's how I know I'm getting old I guess. Kids these days don't know they're born.
I've always wondered if it was perhaps the inspiration for the novel Neuromancer (2 AI's in different continents plotting to combine with each other to form a global super-intelligence)
We got both, so twice as good.
Ah, 'demand destruction', which in sounds positive in theory but in practice will likely mean poverty, famine and 'population reduction'.
You are assuming that a battery is full at 4.2V and empty at 0V. In practice a Lithium Ion battery is empty at 3V. You are also assuming the relationship between capacity and voltage is linear - it is not.
In the developed world we have 'energy slaves' instead; around 100 per person in the USA in the 2020's.

This is arguably the reason why the Overton window has shifted towards the rejection of human slavery over the last century or so, with the growth of fossil fuel use.
Human slavery will thus likely swing back into fashion again in the future as oil, coal and natural gas run out.
That will happen on the day there is enough to go around.
Unfortunately I fear that time has long gone.
As long as the population is growing and/or the (fossil) energy is falling there will never be enough to go around.
I keep reading this, is it meant to be a joke? What is being won?
People are losing their minds at the prospect of oil availability dropping just 20% for a month or two with the closing of the Strait of Hormuz - even just this could collapse the global economy.
So yea, no way is oil stopping or even dipping slightly any time soon.
