One of the main drivers for the plot of the movie is that the main character, Cobb, is trying to plant an idea in someone’s mind in a way that they think it was their own. In the movie, Cobb tries to plant an idea in Fischer's subconscious through multiple dream layers. This is very similar to the way that advertising and other such algorithms work in real life. They attempt to collect as much data about you as they can in order to give you highly targeted ads, even across different websites, effectively in an attempt to guess what you want at that point in time. It is extremely easy for someone to be influenced by these kinds of ads, even subconsciously. Evidently this kind of marketing works, or companies would not do it to such a degree, but it calls into question how far is too far when it comes to targeted advertising. One might argue that the collecting of one’s data for the purpose of providing targeted ads is too far.

In the end, the concept of dream intrusion in the movie Inception is a highly fantastical representation of modern system intrusions and breaches that we see today. The movie does a good job in forcing the viewer to contemplate these privacy issues, doing so through a medium that is relatively easy to grasp the concept of and privacy issues surrounding it.
