By 2040, computers will need more electricity than the world can generate

Reversible computing[1][2]. &amp; I most highly recommend this fantastic lecture on the Physics of Computing:<a href="https:&#x2F;&#x2F;youtu.be&#x2F;OEzuZ6BpC-g" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;OEzuZ6BpC-g</a><p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Reversible_computing" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Reversible_computing</a><p><a href="https:&#x2F;&#x2F;youtu.be&#x2F;qPgveUgK8P4" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;qPgveUgK8P4</a>

I always find it funny when projections decades into the future show straight lines. Even more so when the scale is logarithmic.

In 1894, the Times of London estimated that by 1950 every street in the city would be buried nine feet deep in horse manure.

A human brain runs on 20W. I think we have a lot of work ahead of us

Why is the world&#x27;s energy production a constant value from 2010 to 2040? Surely we produce more energy today than we did 30 years ago. Is this just a chart scale issue?

We&#x27;d probably increase power production before that point, methinks

The Joules&#x2F;year on the graph is a flat line from now to 2040. It ought to read &quot;does generate&quot; instead of &quot;can generate&#x27;.
