I think that’s a very strong argument and a great metaphor, but you forget relativity.

All reference frames are valid - you could say the Earth and the people are moving and the train is stationary, you could say the train is moving and the earth and people are stationary, or you could say they each have a vector moving around the sun or anything else

But when you travel through a portal, the only valid reference frames are you and the entry portal. Your momentum relative to the Earth doesn’t matter - why would it? You can open a portal to the moon and jump through, and we see momentum is preserved. The Earth isn’t a special reference frame, it’s just the most noticeable one.

So let’s pick the reference frame of someone on the track. Let’s look through the portal and say there’s a sign on the other side - as it approaches, you’d see a sign approaching you through the portal. Relative to you, through the portal the sign is moving at 30mph. The portal passes over you - you haven’t moved, but you enter a new reference frame, a frame in which the Earth and everything on it is moving at 30mph

This actually gets me thinking… Is anyone actually working on an aids vaccine? Maybe mRNA could do something there, theoretically it should be able to grant pretty much any type of immunity you can have naturally

Not a feat of engineering, a feat of marketing

Oh, the global economy is going to break regardless. China is physically and economically collapsing right now, and it’s going to have huge knock-on effects

Meanwhile, we still don’t even have a consensus that long COVID is a thing. I definitely feel slightly foggier long after the fact, it seems to me that it might be less about COVID doing something special - maybe all illnesses chip away at long-term health, and COVID put a lot of people in a state much worse than the flu and got us thinking about it.

Or maybe COVID has unique mechanisms, but it seems to me there’s an assumption - why do we assume that once we recover, we get all the way better? If anything, I think it might be the opposite - there’s plenty of people in my life who never felt the same after getting an illness, but no one talks about it in a unified enough way to give it a name

Because immunity varies by disease.

Chicken pox? Pretty much one and done. COVID? Falls off rapidly after 3 months, whether you catch it or get the vaccine

Plus, every mutation is a dice roll on how much existing immunity will apply. It could be exactly the same as the last strain, or the old immunity might not help at all

After tech Jesus posted that, a former employee came out about all sorts of stuff about the work environment were pretty horrible

Yeah, except they federate. They keep lists about who they federate, defederate, and know of in machine readable format
