I have no experience with this, but there are apps you can get which turn the screen from full colour to greytone. apparently it really cuts out the addictive quality for a lot of people.

I think getting good at getting good at things is also good to do at that age. I'm in favour of encouraging kids to study broadly, but I've also ready very compelling accounts of where encouraging a kid's narrow interests got the child to learn ancillary things much more quickly (though TBF, that child was deeply on the spectrum and perhaps not a typical example)

One thing I found when looking into investing in Asia is that p/e ratios are... extreme.

Purchase to rent ratios are also extreme in china. Good investing is tough.

I'm not an expert either, but you might be interested in the book 'Superforecasting' by Tetlock and Gardner - they have done some (IMHO) very interesting research on predictions markets. It might be the kind of thing you're looking to research more of!

Thanks for the recommendation - that does look very interesting indeed! I will find myself a copy and have a read. Hacker News book club comes through again!! :)

Wouldn't we have a robot steer the light sail as it got closer?

Genuine question, this is well outside my wheelhouse.

I think that's the right answer, as it got closer the exact parameters for the slingshot could be refined with images of the system taken a few lightdays out with a strong camera. So we just need that robot really.

Wild honeybee colonies used to exist, though granted they were a new import.

Oh now you're just tempting fate. Surely that distinction goes to the cockroaches?

The ideology of growth being dealt a genuinely humiliating defeat would involve massive depopulation event anyway. It seems far better to shift away from growth-dependent economics before any humiliating defeat rather than hope the people who survive it happen to be well-versed in regenerative economics.

I've started a meetup group for the purpose of discussing how a grassroots effort could shift some of the resources of the growth-economy to a steady-state economy while the former is still in place, but interest has been miniscule in my midsized college town.

The only thing I could possibly see working for what you're envisioning is building it on top of the Neuralink if a version 1.0 ever comes out.

When you say 'fix' do you mean 'prevent a two-degree shift' or 'transition to an zero-net-emissions economy'? Or do you mean we can avoid some survivable threshold higher than two degrees?

I agree that useful action is possible and important, but I'm starting to feel that our last chance to avoid catastrophic climate change was sometime last decade or the one before.

I mean both, first 'prevent a two-degree shift' then 'transition to an zero-net-emissions economy' and finally even negative emissions. This was almost solved in the 1980s and wasn't but that's a sunk-cost fallacy. The chips are down and we are where we are, so let's roll forward and get this solved.
