Dude, if someone here is “well akshually” that is surely you. When people talk about people on the internet that are annoying to meet - that’s you.
But apart from that. You are simply mistaken in a lot of things or are projecting so hard you may as well have an HDMI input.
Nobody said 50s era or even modern diesel subs or their other non nuclear equivalents are “better” than a nuclear sub in all ways but in some situations, e.g. coastal defense and operation sin shallow water, they may be better suited to the mission than a nuclear sub that is 4 times as large.
In addition there are economical considerations. If I can buy 4 diesels for the price of a nuke sub it may be better for me to have 4 diesels who can lie in wait at 4 places at once.
The question is mission fit of the asset. A ship will sink all the same whether it was sunk by a 2 billion USD Nuke sub or by a diesel on the way to the wrecker that had a really really lucky day.
Now you (and GN) have to decide… Either Linus is supposed to give his take and opinion on items they review without any regard to relationships or are they supposed to give this product preferential treatment because of who produced it?
While GN is certainly right in several points (and LMGs selling of the prototype was a really bad oversight for which they need to pay), Linus take from "no cooling performance is worth it at this price point and nobody should buy this) is his opinion and it is not without reason or logic. And GN tells him 5 minutes earlier to do exactly that - give his opinion and take without regard to others, the community or the producers of the products in the name of “journalistic integrity”.
