I agree. Roddenberry was a genius at inspiring enthusiasm for a vision of the future that is delusional in the Maoist way and in other fundamental ways.
Our critics (e.g. thoughtful sci-fi authors like David Brin) should have criticized Roddenberry much more strenuously than they actually did.
Yeah. Luckily the parts of Star Trek that inspired people were the gadgets. It's common to hear Valley startup founders talk about seeing something in Star Trek and then thirty years later it's their product launch. The social side was much less impactful, you never hear people talk about how to create the Federation, probably because the writers never explored it (as they couldn't).
