The human species has some pretty spectacular systems built into us to achieve mental, emotional and physiological states that most of us are not even really aware of. 

We also have systems and features within us that make us very vulnerable to being influenced and ‘programmed’ into behavior that is not reflective of our most evolved neural circuitry.

Technology is interfering with and manipulating those systems. 

And the more we get to know how technology is interfering with those systems, the more we can get control over our internal state rather than let the tech companies (who do not have the best interests of the human brain and nervous system in mind) hack into our vulnerabilities.
