I feel as though this realisation was made among certain people (probably a surprising number of them) decades ago.

The more power and influence you have, the less you are inclined to change anything.

Therefore, capitalism, if unregulated, must inevitably lead to the extinction of humankind.

Figuring out how to act as "one" on certain matters (rather than a bunch of seven billion merciless competitors who will stop at nothing to get one up on their neighbour), such as climate change, will be the greatest and most decisive challenge humanity will ever face.

It'll be interesting to see where that goes.
