You have a point. I would further add that private ownership of these things requires capital concentration that cannot be healthy for society.
On the other hand, are we replacing public with private infrastructure here or is the private sector filling gaps where we didn't have any public infrastructure before in the first place?
The end of the UN seems plausible if we continue to move from a rule-based world order to a power-based one. For the same reason, there is little chance we will see the end of the EU. No European country is sufficiently powerful to really matter on the world stage, a more united Europe has the potential to be a significant world power though.
The scaling laws are also power laws, meaning that most of the big gains happen early in the curve, and improvements become more expensive the further you go along.
LeCun has already proved himself and made his mark and is now in a lucky position where he can focus on very long term goals that won't pay off for a long time (or ever). I feel like that is the best path someone like him could take.
If you can't manage it every day, a less frequent habit will still have benefits.
I've been doing strength training once a week since the pandemic startet, and it has been great. Obviously I could have made much more progress with more frequent training, but I still look much better naked and more importantly, I feel much better. So many random aches and pains have just disappeared.
