Dislikes are good not just for identifying bad videos, but also good videos. You can see it in the like/dislike ratio. The higher the better, videos with ratio around >98-99% have very high probability of being good etc
Comparison of likes to views works well enough. Actually, they don't even need likes, they can understand good and bad videos just by analysing how long viewers spent viewing the video.
Likes (and dislikes) are needed mostly for viewers who might want to feel helpful.
Yes, I was wondering that very much myself. I remember talks about ramping up production preemptively, starting from spring, to have large stock of vaccine available when they are approved. Bill Gates talked about that specifically, taking like first 5 most promising vaccine candidates and starting production ramp up immediately, even risking the possibility they will not be approved and wasting some money. I thought "Finally, some good strategy". Money risked with such an approach would still be minuscule compared to losses due to pandemic and covid relief funding.
But looks like that didn't happen, which is just another sign how badly world handled the pandemic.
There's an article related to this:

Pfizer and moderna were not in the most promising vaccines list. MRNA was too new and untried. I'm not sure why Oxford/az wasn't ramped up more though, they were the ones everyone was waiting for.
Moderna received WARP funding though, I think they definitely were on the list of most promising vaccines. There were 6 most promising western vaccines: Biontech, Moderna, J&J, Oxford, Novavax and Sanofi. It was clear they were the ones needing preemptive production. Sanofi didn't play out, but others are doing ok.
Youtube's auto CC feature gotten very good lately, I think it can handle most of the stuff with clear sound. So hopefully auto CC will help to solve this unfortunate paradox of accessibility.
Kids are not in risk group for this virus though. Check out graphs at https://www.euromomo.eu/graphs-and-maps - with all the lockdowns etc going on this year, mortality for 0-14 age group even decreased a bit.
Kids are too big a fraction to dismiss. And they are massive infection vectors. A kid gets sick, everybody else in the family will get sick. People with kids know that. Teachers know that. Doctors know that.
Yeah, intelligence service of both(and more) countries probably do that kinda of stuff on a regular basis, that's why they exist, but I don't think that had hardly any effect. "Russians, Russians", "Trump is a puppet of Putin" etc was a convenient scapegoat for losing the election. But problem of democrats was not Russians, but the fact that half of the country was ok with voting for Trump. And split was there long before and just growing with time, but Americans are doing great job splitting up themselves. Like with anti-sanders higher up demparty struggle. Both sides are now so politicized they are ready to bend reality and view everything through hate to the opponent.
