At some point we will have AI designing and AI delivering ads, and while we may have AI designed to prevent us from having to watch ads we don't want we will also have AI that watches everything, gathering and filtering information that is too much for us to handle but tuned to our needs since it's "our AI". Then the race will be that one AI wants to trick the consumer AI into giving their information more weight and attention.
So instead of the race humans against humans we'll have a race humans => AI ("sellers" of anything, from goods to news) => AI (consumers) => human (us).
It's going to be a lot more complex: Right now all that people on both sides have to know is human psychology. In that future they'll have to understand the potentially far more varied world of possible AIs - and if that isn't enough the complex interactions between them and also between the AIs and the humans.
Are we creating the diversity and complexity that we remove from the biosphere (the ongoing mass extinction and/or reduction of many species) anew but in a completely different space? In addition to technical systems we are also getting much better (and better faster!) in controlling biological systems, creating our own ideas. At least some programmers of the future will write their code in DNA - or possibly even something more complex, something that can encode completely new proteins that the current code can't represent. And then there's combining biology and technology... an explosion of complexity and diversity?
I studied CS more than two decades ago. I kept up to date and continue to do the odd course in my field, but what I consider an amazing experience (for an IT guy) was when I spent the last few years taking hundreds of hours of courses in biology and medicine. Looking for new ideas? Take an introduction to biology and genetics course instead of learning an only very mildly different programming language, for example (free): https://www.edx.org/course/introduction-biology-secret-life-...
