No one knows for sure what will happen in the future, full stop.
but tbh, at this point, I'm just not feeling that optimistic. Give this shit 10 years, and I feel like the human brain will pretty much be hacked from a marketing/propaganda perspective, and Russia, the GOP..whoever, insert blank...can pretty much put whatever they want out there and 25%-60% of the population minimum is going to be helpless to it. We're too fucking stupid, we're stuck in our American dream, we're in a magic technological bubble we don't understand, and we just ain't in control.
Americans as a whole do have the power to say, "OK, we fucked up, we need to catch up, our world is rapidly changing we need to come to terms with our (in many ways horrific) history and a future that is anything but stagnant, and that has challenges that are bigger than we can solve with 'AMERICA #1, FUK OFF, GET FUKT FOREIGNERS AND/OR MINORITIES', and we need to educate ourselves and our children about the new and still-changing nature of propaganda and war in the 21st century."
We might! But, I'm not just very confident we will do it in time in this point. I'll feel lucky to live in a world in 20 years in which some other country/union is able to save us from ourselves.
