Isn't that a 'necessary but not sufficient' condition though? I'm thinking principally of the struggles in Zimbabwe here.

It's been 15 years and I'm still not sure if MMT is an accurate description of Economics, a persuasive analogy, or convincing bunkum.
I love how memes (in the Dawkinsian sense) work. Lots of people have enjoyed this, but I can imagine this being quoted as the original is lost to the sands of time.
Young people everywhere thinking that Aquaman was someone who just bought failing assets from everyone.
Jumping on here, because this is often overlooked. If you didn't know the title of the film, and someone played the first 20 mins to you you'd expect a hallmark film. Going to see the estranged wife, trying to repair a relationship, the awkwardness at the Christmas party.
The whole thing subverts Christmas movie tropes. It's not just an action movie set at Christmas. It's a Christmas movie which gets hijacked.
Even the final scene plays on the parody with the 'snow' falling, the comedy comeuppance for the nuisance bad guy, and then they kiss and drive off as 'let it snow' plays.
I think a lot of people in this thread are overstating the suspicion of outsiders. International trade has existed for thousands of years. There was even limited tourism in the middle ages. It would be rare to encounter people that you couldn't communicate with, but I don't think you'd be automatically sacrificed.
I'm in London, so would fare better than most as they would definitely be familiar with outsiders. That said people in many of the old European cities would likely be able to blag their way to local universities. Oxford definitely already existed 650 years ago so I'd start by heading there.
I think all scholarly writing was in Latin at the time, so I'd need somebody to translate, but (with luck) I could move maths on a couple of hundred years. I reckon I could get basic electricity going too. Obviously the more you said upfront the more suspicious people would be, but if you drip-fed knowledge over a few years, trying to let the steps rest upon each other you could probably share a lot of what we know today.
