Re subs, the water has to be moved out of the way (and then back again afterward). That would require an insane amount of power for anything as large as a manned submarine. I strongly suspect this is meant for torpedoes only.
Re "wing in ground", I'm pretty sure you mean "wing in ground effect". Dirt is pretty draggy, y'know.
Professional journalists are trained to worry about "fairness”, not truth. Reality, they are told, is socially constructed, and there is no such thing as objective truth.
Fairness means reporting “both sides” of a story even when there are 3 or 4 sides, or when it’s obvious who is lying and who isn’t.
If journalists were interested in truth, they wouldn't pretend to be impartial (they’re human, of course they have opinions of their own). Instead they'd openly admit their viewpoint and let the reader judge their arguments.
There are still countless newspapers in the US with “Republican” or “Democrat” in their title. I suspect the relatively high esteem which journalists enjoy is a legacy from the era when these newspapers were founded.
Before the rise of “professional” journalism in the middle of the 20th century, truth was assumed to exist (even if it was difficult to find), and publishers were proud to announce their political allegiance.
Re: an invention becomes inevitable given the state of the art
That's my point - most "inventions" are the result of reasonably bright and creative (but by no means exceptional) people doing the obvious thing under the circumstances.
This is why we constantly see multiple independent re-inventions of the same thing - news of the earlier "invention" takes time to trickle out to the wider community (esp. young people who aren't well connected).
So, those who haven't heard about it re-invent it themselves.
Such multiple independent "inventions" ought to be the definition of "obvious to a person having ordinary skill in the art", thus making any patent on such inventions invalid.
As mentioned re an earlier post, I personally recall using email prior to 1977.
But that doesn't mean Ayyadurai didn't invent email long after that.
It is quite possible, if he was 14 years old, that he hadn't heard about the many pre-existing email systems, and independently re-invented it. After all, email is a pretty obvious thing to do once you have a computer network.
I had no idea that in the Soviet Union when you needed an electric drill, you just told your wristwatch that you wanted one, and 120 seconds later a flying robot would drop out of the sky and hand it to you.
If so, Soviet technology is vastly underappreciated.
