Ah yes, the real danger to the world isn’t a powerful man feeling ambivalent about our survival. The real danger is society using that moment as propaganda.
This regarding Thiel, a man who most recently tried to make a “Greta Thunberg is the Antichrist” meme stick.
Hesitating to answer a question that may have nuance is not being “ambivalent”. He literally says “there’s multiple questions implicit here” in response to the question asked of him. I genuinely think people like you making sweeping assumptions about others are way more dangerous. People who refuse to critically think or analyze a situation and jump to conclusions.
You pair that with his behavior and you can see pretty clearly the guy does wants to control the world. Stop trying to see this in isolation of that one event.
Not to mention that he and his cohorts had such close ties to Epstein that I find it impossible to imagine he didn't know exactly what was going on. This is someone who's known for building profiles of anyone who mentions him online, not some ambivalent rich guy.
Question 1: If a human modifies with themselves with enough sci-fi tier technology are they still "Human"? (And therefore if humans "ascend" past their biology, humanity technically wouldn't survive)
Question 2: If a person cannot conceive that the 1st question is an interesting question, with multiple nuances, are they basically an idiot?
The question wasn't "should all humans not modify themselves", but "should humanity survive".
We currently legally protect mostly pre-contact civilizations like Sentinelese, so it stands to reason that regardless of what some people choose, other people will forgo transhumanist modifications, and "humanity" will survive regardless of what technology occurs or where your definition ends.
Unless of course the end goal is only a few billionaires get to live with their AI ppowered city states at most using servitors and decraniated as robots.
