The Economist magazine uses a diæresis (two dots) in words like “coöperate” and “reëlect” to indicate that both vowels are pronounced separately, rather than as a diphthong. This is considered old-school and uncommon though.
There's lots of posts on HN for developments and companies doing OCR and Document Extraction. It's a classic CV problem but still has come a long way in the past couple years
Around a month ago there was a PINN post[1] on here and there was a healthy amount of skepticism in the comments. Even in the toxic positivity of LinkedIn, commentors say they're overhyped when a ML "Influencer" posts that one GIF with a MLP and PINN fitting to an oscillator. I would be interested to see what they're actively being used for.
Not sure why South Koreans don't try to get out, since education is super strong they could probably move to USA or some other country with more money, easier working culture, and relatively lower housing costs
I can't speak to attitudes, but when I was in grad school years ago, Koreans were very well represented in my program. There were fewer Korean students than Chinese but more than Indian. Generally they do well in both coursework and research so there's likely at least some opportunity to stay in the states, assuming they don't have obligations back home.
