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.

"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.

The Future's Bright. The Future's Onion.

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.
