Mustafa Suleyman has pointed out that in tech circles there's an extreme aversion to pessimism.

It's almost taboo; if you do it, you're not a member of the tribe.

The aversion is so strong that we can't even sit with the idea that there might be externalities.

Acknowledging externalities feel pessimistic.

But externalities are real.

They emerge automatically, even if you don't intend for them to.

And they can even be good!
