Project lead of LessWrong 2.0, often helping the EA Forum with various issues with the forum. If something is broken on the site, it's a good chance it's my fault (Sorry!).
Yeah, I've considered this a bunch (especially after my upvote strength on LW went up to 10, which really limits the number of people in my reference class).
I think a whole multi-selection UI would be hard, but maybe having a user setting that you can change on your profile where you can set your upvote-strength to be any number between 1 and your current vote strength seems less convenient but much easier UI wise. It would require some kind of involved changes in the way votes are stored (since we currently have an invariant that guarantees you can recalculate any users karma from nothing but the vote table, and this would introduce a new dependency into that that would have some reasonably big performance implications).
Academia pre the mid-20th-century was a for-profit enterprise. It did not receive substantial government grants and indeed was often very tightly intertwined with the development of industry (much more so than today).
Indeed, the degree to which modern academia is operating on a grant basis and has adopted more of the trappings of the nonprofit space is one of the primary factors in my model of its modern dysfunctions.
Separately, I think the contribution of militaries to industrial and scientific development is overrated, though that also would require a whole essay to go into.
Me and the other people working on Lightcone + LW are pretty interested in working in this space (and LW + the AI Alignment Forum puts us IMO in a great positions to get ongoing feedback on users for our work in the space, and we've also collaborated a good amount with Manifold historically). However, we currently don't have funding for it, which is our biggest bottleneck for working on this.
AI engineering tends to be particularly expensive in terms of talent and capital expenditures. If anyone knows of funders interested in this kind of stuff, who might be interested in funding us for this kind of work, letting me know would be greatly appreciated.
