I don't expect perfection from Musk, but it's easy to imagine he does most everything with good intentions, or at least no malice.
I'm a fan of anyone willing to go broke for what they believe in though and I do recognize his social influence is so strong that it would be very difficult for any human to handle that without getting a god complex.
The reverse, more worryingly, is also sometimes true.
I'm in the "hero" camp, yet I still made that comment about neuralink. I would probably be more shrill in my concerns if Zuck was doing neuralink. But ultimately, I don't think the individual matters much. The creepiness of social media ads and recommendations systems is mostly because of what those platforms are, not the individual publicly leading them.
