To what extent is language in Orwell's 1984 similar to today's language?

In George Orwell’s dystopian novel 1984, the official language is Newspeak, which is being integrated among the populace during the events in the text.
Newspeak is characterized by a simplification of Standard English whereby words are often abbreviated and mashed together to form new words. Newspeak helps the Party control the people via limiting the ways in which they have to describe things. It places the power of language, a strong propaganda tool, in the hands of the totalitarian state.
This is similar to the evolution of language in today’s world because of technology’s impact. The rise of texting and social media have created the need for abbreviations and lingo that previously didn’t exist, such as “u” for the word “you” and “tmw” for “that moment when.” These substitutions and acronyms have become their own form of shorthand in how people communicate over the internet. This has trickled down to young people, who might even accidentally use texting lingo in formal writing. This has caused a lot of hand-wringing over the devolution of the English language, but what it actually shows is that language adapts over time.
