Honda seems to do fine with it, yet VW has a reputation for early failures...and they historically use some of the thicker oils on the market.
0w-16 makes your engine last 2x longer?

My OCD is triggered!I drive a 2020 Honda Accord Hybrid that is spec for 0W20, but I am using a mixture of 2 quarts 0W16 and 2 quarts of 0W20. My next oil change will most likely be 3 quarts 0W16 and 1 quart 0W20. Someday, I plan to do all 4 quarts of 0W16, but my car is NOT spec for 0W16, but nothing will happen to my car using 0W16. Besides, it is not oil that I plan to use forever, but I want to know that I can mix 0W16 any time with 0W20.
I like to hypermile and when I hypermile, I get over 60mpg.
And this is my stash of oil for my next oil changes ahead of me.
And this is what I have been getting so far on this tank of gas since I changed my oil using 0W16 for my first time and starting off with a new full tank of gas. I am getting over 63mpg so far.

"Startup wear" isn't the main period of wear, warmup is, where materials are heating changing shape and size to get to where they are supposed to be at operating temperature. Since oil pumps are positive displacement, there's very little difference between the time it takes for a 0w-16 and a 0w-40 to get to the top most part of the engine.
Engines don't "wear out" because of "startup wear", it's something that's often harped on but doesn't really have any relevance.
I think you are messing up tolerances and clearances. While machining tolerances have steadily improved sine the 70's for the most part (the exception being bulk-fit pistons vs hand fit) clearances have remained the same. Engines are no "tighter" than they were back in the 1960's, so no, they don't need thinner oil. Improvements to rigidity, coatings, and surface finish have enabled the use of thinner oils, particularly when coupled with oil temperature control.
OEM's are also motivated by CAFE in North America, which has been a significant driver in the pursuit of thinner lubricants, which improve fuel economy, most significantly during the warm-up and around town where oil isn't up to temperature.
Yet you just said you personally leave it up to people that are smarter than you. What if that person's engine calls for 10w-30? Or an even heavier oil like 0w-40?
Yes, as I said earlier, I refuse to watch his videos.
And don't forget the 300% increase in fuel efficiency. You'll be saving so much gas that you'll periodically have to pull to the side of the road and siphon off a few gallons off lest the gas start pouring out of the gas cap.

honda has 0w8 already, so that's 100x longer
0w0 would be a straight 0 weight base oil with no plasticizers and other additives to achieve a multi-weight oil.
Don't laugh. I was offered the opportunity to try an experimental 0w-(-10). Fixed a worn cam, blown head gasket, and a ding in my driver's side door.
