Agreed. IIRC the mechanism for anesthesia in unknown to this day. In fact, medicine as a whole is very pragmatic and time and time again prefers using techniques with unknown mechanisms but proven results than waiting for a reasonable scientific explanation of what’s going on.
Perhaps I'm in the lower half but I do not understand what point you're trying to make. Are you saying that as some higher plane of understanding Tao is actually correct? My thinking is that a simple counterexample would be sufficient - i.e. are there medications that people use for which the mechanism is not understood? There are many such examples as others have given in this thread.
Initial discovery in medicine is largely "try and see what seems to work". But there are many reasons why scientific inquiry just doesn't stop there and also seeks to understand the underlying mechanisms. For example, a naturally occurring product may be too difficult to harvest on a large scale. Or, a sample might not be sufficiently representative to uncover potentially deadly side effects or drug interactions. Humans are fundamentally unsatisfied to take everything purely on faith.
Now I’m even more confused, perhaps we are in agreement. My position is that there already exists many such medications that no one knows how it works. It also used to be the default way medicine worked. Lots of things that work were found though observation of trial and error.
My position is that Tao is not only wrong on this but his example makes the opposite case.
“ They understand nothing at the level that Tao means. Literally nothing.”
Was this sarcasm and I missed it? Because not only do I think I understand at the level of Tao I also think he is wrong and not understanding something.
The person you are replying to is trying to make the following argument.
Tao is intelligent. Intelligent people have higher standards for understanding the world, such as assuming that the mechanism behind medicine are well understood. But most people are not intelligent, so they don’t understand things like medicine at the level Tao presumes.
I don’t agree with this argument, just explaining it.
Where that falls down is that it is not even a good idea to limit the use of medicine to only what is well understood - i.e. that would be very un-intelligent. There is nothing higher level about it, quite the opposite.
Not really… Theoretically, you could get it issued in a third country under very restrict conditions (renewing to the same class, in Mexico or Canada, force majeure, etc). However, the likelihood of it being denied was considerably higher, so basically all immigration lawyers strongly recommended going back to the home country.
The recent policy change ended that possibility altogether.
This matched my experience. 2002 I renewed in Canada with no issue. 4 years later I had to go back to my home country as I was told by my immigration lawyer that unless I had a connection to Canada, they would redirect me to my home country.
at least for Indians, going to Mexico/Canada and renewing to the same class were both very large use cases. consulate appointments in the home country are super backed up.
Not _this_ time but they were targeted previously: banning up to 75 countries from issuing visas, adding a $100k fee to the application, forcing visa renewals to go through consular processing instead of change of status, etc.
The end goal is to do end migration as a whole (especially from “certain places”) and expel all “undesirables”. To get there, they will test the waters, get the right precedents and judicial orders in place, and move the Overton window enough so the public sees these actions as “business as usual”.
