It's easy to draw parallels between the concepts of the novel and the state of the world today, and technology plays a huge part. It's incredible. And frightening.
For instance, you can, to an extent, equate IoT and smart home devices with Telescreens. It's not hard to get access to these, and suddenly, you have a window into the most intimate parts of someone's life. Keep in mind, none of this is regulated.
In many lesser developed countries, people are persecuted/prosecuted for their beliefs and opinions: Thoughtcrime.
The Chinese government is essentially Big Brother, what with constant surveillance, authoritarianism, complete lack of privacy and people being given "social scores" by computers that analyse their actions, and these scores deciding what they are and aren't allowed to do.
Newspeak: Seen in many, many nations, but for example, concentration camps being called "re-education camps" in China. Here's a list of real-life examples: http://mattjennissen1.weebly.com/uploads/7/1/0/7/7107262/rea...
