Disagreement is healthy. What was unhealthy is that it was dangerous to disagree. People who thought we should just ride covid out were, more often than not, simply unaware of the nuances of covid vs a cold or something similar. People who thought we should hide in our homes until it was eradicated were similarly unaware of the implicit harms of that choice. A healthy discourse with people willing to concede and comp…

We were all told to shut the fuck up and listen to a handful of cherry picked “doomsday experts” who refused to follow their own data, didn’t follow their own science and refused to acknowledge that society has millions of problems beyond one very single, very specific thing. And if we didn’t follow their edict’s or if we were to express any doubt of any kind, we were evil alt-right grandma killers who deserved horri…

> We were all told to shut the fuck up and listen to a handful of cherry picked “doomsday experts”

No, you were told to out aside your opinions and allow people educated in epidemiology to guide a rapidly changing situation. It turns out the there were too many people with a chip on their shoulder to make the policy recommendations effective.

> if we were to express any doubt of any kind, we were evil alt-right grandma killers who deserved horrible Covid deaths.

Pointless hyperbole.

> no acknowledgment of the harms they were causing

Such as?

> What the Covid “side” did was abhorrent and history will not look fondly on them at all.

Reading between the lines it seems like you have many baked in assumptions that distort your perception of the event.

What scares me so much about the Covid debacle is that despite all the information that's been coming out about how most of the restrictions placed on people -- like hindering people from gathering _outside in the sun_ -- and effectiveness of both pharmaceuticals and PPE's -- of which I won't name any because then I'll be booted out of here quite quickly I imagine -- despite all of this data, government hearings arou…

Early in the pandemic we just didn’t know what the death rate from Covid would be. 1%? 0.1%? Or maybe 10%? How many people get long covid, and how bad is it? Does it kill the old or the young? What is the death rate for people who get Covid, and can’t go to hospital because there are no beds? If Covid were to wipe out 10% of the population, all the draconian measures make a lot more sense. Slow it down as much as pos…

Locking people indoors with limited ventilation and no UV radiation is never going to be a reasonable approach. Why? Because UV radiation kills viruses very fast and thus drastically reduces their capacity to spread between hosts. Not to mention the obvious factor of air circulation in a near-infinite dimension thinning out particles per cubic meter within seconds. Also turns out fresh air is generally good for sick people too. So is sunlight.

Studies on the coronavirus circulating showed this at the very beginning of 2020. And that’s just one of the anti scientific measures that were taken.

Check out https://sinerider.com/ too! A friend of mine who helps Grant Sanderson sometimes with 3B1B stuff built it, it's an awesome math education game like LineRider but using formulas to build the tracks.

I love both 3b1b and SineRider, both have had more impact on my intuitive understanding of function composition than anything else.

This is only "obvious" with the benefit of hindsight. There was a mountain of rushed studies early on reporting all sorts of conflicting "facts" about covid. Of course using what we know now, you can look back and cherrypick a lot of great stuff from the pile of early results. But that doesn't mean you could have done the same thing in early 2020. How could you tell which studies to believe? Everything was rushed, had small sample sizes and nothing had been replicated yet.

At the start of 2020 it wasn't clear how long viral particles stayed airborne, and whether you could even contact covid from breathing it in, or if you needed physical contact of some sort. I remember one scare where people were worried you could catch covid from the cardboard used for amazon packages - before we realised covid dries out and dies if it lands on materials like that. Thats not true of all viruses.

Government policy, science and software share something in common: They can happen fast or happen well. You can only pick one. Rushed science gets small things wrong. Rushed software is buggy and brittle, and rushed government policy makes mistakes.

Its easy to forget, but the start of 2020 was a madhouse.

This is amazing, thanks for sharing!

Efficacy, maximal effectiveness over a large population, and because it works better at scale than other solutions.

I was under the impression that our education system is more about keeping children off the streets while both parents go to the office/factory than really educating them. This was especially visible during covid.

In that sense I agree with you: videos won't do the job.

On the other hand there is this one guy making videos that, I believe, reached way more people than any single teacher would. How does that count for scale?

Can we agree that there is room for both and that these videos are a nice addition?

It was impressive how he spotted a bug in his rendering engine and found a workaround for it in realtime! https://youtu.be/rbu7Zu5X1zI?feature=shared&t=693

In larger companies this is how arsonist-firefighter engineers look impressive... fixing a bug they are responsible for while in a highly visible position

I've been in this situation before, there's a fair amount of "we can do the thing in x time but it'll have these issues, or do it right in x+y time." The quick option gets chosen, things chug along happily for some time, then we hit the limitation and I remember what the issue was. I couldn't even say that the decision to do the quick thing was the wrong one.

To me it appeared more like he was aware of a limitation in the new rendering logic he was working on in the backend, and that he knew a simple (high level) workaround. Still impressive work :)

The workaround that looks like "disable the feature I was working on". x)

In the early 2020s, studies have shown everything and their opposite, so you can cherry pick anything that supports your view. I find it was a particularly interesting time because it showed how "messy" science really is. In normal times, you typically don't see scientific results before you have at least some amount of certainty. Some research get through the cracks (ex: LK-99), but not to the extent of what happened in the early days of the pandemic.

Also covid and other diseases spread well in open air summer festivals where UV is at its peak. And for covid specifically, we had peaks in the summer, where, again, people tend to get out and UV is high.
