Since XBX_X lied to your face and brought you the wrong video, here is the link to Tik's actual video.

The AI videos allow the addition of an approximation of Hitlers voice His regular speeches would change tone dramatically over the course of the long presentation, and the way he used German grammar meant that his sentences never sounded like they ended until he got to his specific point, so those parts are lost to the AI. Reading the speeches, frankly, makes him sound actually more crazy than he would have intended, especially in English, where it can't help but come across as a rant.

The translations are the translations. They're pretty much going to all be similar, the problem is that Hitler used some National Socialist vocabulary that doesn't have any direct translations, and zero connotations, into modern English. Gleitschalung might simply be called "synchronization" in English but means something more like "a mass, sudden, snapping into a different state that allows the thing to move in completely different direction all at once", particularly within the NatSoc ideology. Similarly you might get "Autarkey" or a German word for it, but this term is an archaic Leftist ideological term that isn't used in modern vernacular anymore, even on the Left, so translations might not convey it properly. It might be just translated to "Self-Sufficiency", when it really means "An insular economy so complete and productive that there is no possible need for trade, meaning that it's borders are fully closed, preventing the setting of prices by outside capitalist forces." This concept is so wrong that the Left actually abandoned it, but it forms a critical component to National Socialist ideology, and Hitler's objectives in Europe.

As a result, most translations have a nasty habit of accidentally moderating his speeches because of the missing context that the directly translated words lose. Both the AI and the translators do this.

Tik's argument is specifically that the reason that some of Hitler's speeches have some appeal is because the Left's lies about Hitler to try and scream that he was a hypercapitalist, and the censorship of his speeches in some countries, have caused blowback... particularly among people who believe that socialism and the politics of resentment have appeal. Those things have appeal specifically because the Left grooms society into making them appealing. To inoculate the public against Hitler would be to inoculate them against Socialism & resentment-politics; so they chose to censor and hide so that Socialism can be defended.
