Try try try, go Paul go!
The bright side: in terms of people who have played a role in learning others genuinely creative action, I'd bet you are way up there near the top on the list of currently alive humans, despite the lack of that mainstream billions-level notoriety. For every property or project directly or indirectly impacted by your work you do hear about, there's probably 100 to 1000 that you don't. Not enough?
Say you include other people doing similar things in your tally for "success in the empire." Do you see your work as part of a global effort, with yourself being an individual in a bigger picture where your name notoriety is basically unnecessary? If it is necessary to the wish, careful with the fame thing. It will probably never be enough.
And continuing down the darkside...
'unfulfilled wish' can be another term for the root cause of addiction. Yes sir, they can be toxic. Ambition; tread carefully. Emphasize most desires are not part of some immutable core of a human, most individuals who haven't become completely habitual reevaluate their goals, desires, wishes, and ambitions occasionally.
So the "perpetual goal is to cause change at the level of billions of people." In 1 lifetime I assume? (haha.) I see a shot in the dark where you can't evaluate the probability of hitting the target, not something to get disappointed about given the wish may be physically impossible due to the billions of humans that aren't going to change unless they must in order to survive. But that doesn't mean don't try.
Mike Lafay pointed out a lot of what this solution is up against. I'd emphasize that Gert, as far as moneyed civilization is concerned, is bad for business. Say we are aware of paid corporate social engineering trolls, there's also a series of youtube videos "Dead Internet Theory" (1, 2 and 3) put together by "All Time" channel that recently updated my perception of "the internet." Despite the title, it's not a theory, and the pro-established-business bot generating algorithms will not be promoting Gert. I'd bet, that if these channels of communication don't change, Gert is not going far in them.
Back to the bright side, if not already, a near critical mass of smartphone carrying humans are aware that all major corporate outlets, social or otherwise, are only saying what will generate sales, even if it's a lie. So there's a decent chance for a mainstream alternative in which Gert can flourish in the nearish future. To me, the great channel you created here is already so much!
But don't mind my milder ambitions. Carry on
