Orwell was a prophet, indeed:

<< ‘Don’t you see that the whole aim of Newspeak is to narrow the range of thought? In the end we shall make thoughtcrime literally impossible, because there will be no words in which to express it.
.......
The whole climate of thought will be different. In fact there will be no thought, as we understand it now. Orthodoxy means not thinking—not needing to think. Orthodoxy is unconsciousness.’ >>

This, BTW, is one of the significant reasons the left hate Trump so much. Quite a few topics that had been forbidden to talk about in the public arena became permissible again, even before he was actually elected. It is very useful to remind ourselves how different the atmpsphere used to be in this sense.
