Hello, I work in technology policy.

I definitely think you raise interesting questions that are on most global leaders' dockets right now. I also think that academia isn't the only or the most relevant place to address these questions. A big reason for that is that academia has always been a bit of a laggard, whereas technological change is becoming exponential. Most interesting tech research isn't being done at universities. It's being done at private companies. Most of the interesting partnership and tech transfer solutions aren't being provided by universities (or governments) - they're being done by small-scale, agile, increasingly for-profit orgs. Human-computer anything is also an emerging field in an emerging phenomenon, and actually no one, including yours truly, knows what is going to happen. For myself I've decided that it's more interesting to be where the action is happening rather than to be studying it from a distance.

I also think that deciding that you want to write a book about this stuff is a bit front-to-back. You don't write a book and then become somebody - you become somebody and then you write a book. In other words, do something cool, and the book will come. fwiw in the current zeitgeist, people would be more interested in a book by a top UX designer than in a book by a top professor. The world is going to change by a lot, and the patterns you see right now won't be the patterns that work in 5 years from now.

As for what you should do, you say you read and research on these topics in your free time - so keep doing that. Branch out from pop nonfiction to research articles, white papers, policy docs. Go to some meetups. Talk to people in the field! In the meantime, I encourage you to think of institutions not as monoliths, but as dynamic platforms. Once you hone in on the type of work you want to do, think about whether academia will give you the platform to do it - or maybe something else will. Maybe multiple things will.

And, do get work experience in your field after graduation. You're still very young. You aren't losing anything by not going to grad school right away.
