This post made the rounds at USV this week and got us thinking about declining fertility rates around the world. While I am sharing that link with all of you, I don't agree with the author's conclusion about the inevitability of extinction. I think humanity is an extremely complex system with many self-correcting mechanisms in it.
But the charts in the header of this blog post are worth paying attention to.
I was emailing with a friend about this earlier this week, and he said that three charts he is staring at right now are 1/ global installation of solar, 2/ declining fertility rates, 3/ massive adoption of AI.
My friend is a very astute observer of history, technology, and the interaction between the two. I pay attention to what he pays attention to.
If the population of the world is going to be declining, not growing, and if we are adopting cheap, and getting cheaper, energy at a very rapid pace, and if we have technology to make everyone massively more productive, what kind of world does that look like?
It is a world very different from the one we are living in now. Pressing issues like the unaffordability of housing, for example, can change quickly if we are living in a shrinking world, not a growing world. And the need for robots that can do the work of humans will be a good thing, not a bad thing.
Of course, that doesn't mean we should ignore and stop working on the affordability of housing. But it does mean that at some point, those won't be our most pressing problems and humans do have a habit of fighting the last war, not the next one.
Being a venture capitalist gives us the privilege of focusing on future challenges more than most. And that is why I am going to incorporate the idea of declining population into my thinking more than I have been doing.

Hi Casters. I wrote about the implication of declining global fertility rates this morning. https://avc.xyz/declining-fertility-rates
did global fertility rates declined this morning???
tyvm for sharing the unruly post. a feast for thought
how is the idea of population decline impacting your thinking?
supply and demand drives much of economics. less demand has a lot of implications.
That's wild. I agree that the idea that humans are going to go extinct is crazy. If population fell even, say, 10%... it would massively change incentives. Still, the idea that we're not on our way to a 'Soylent Green' future is compelling a chin scratcher
Great job my friend
