This is the most common scenario. That’s why can’t compare Vision Pro with the iPhone. First iPhone was limited yeah but those who bought it loved and used it all the time. Word of mouth setup the success of later versions.

I have the opposite impression. I have consumed tons of hours of interviews with Elon and he comes off as more technically sound and speaks more substance than any other large org CEO I can think of. Karpathy worked directly under him. I haven’t worked for Elon but know people that did and experience is similar. What makes you think you are right?

I was part of the temple build last year and cleanup is extremely serious. We spent two days cleaning after the burn with magnetic rakes looking for minute pieces of metal. We take samples of dirt at different spots and count the number of MOOP fragments to measure progress

How come? We give IP law / copyright legitimacy but it’s not clear to me the more I think about it. If you draw something you def own the physical drawing but owning the idea of the drawing during your lifetime feels strange to me. It’s also a very recent invention and humans created art before and will create after.

I spent most of my career in the open source world and doesn’t bother me models are trained on my output. Should I feel differently? It seems there’s a kind of ego or emotional attachment to the output that is more common among artists than devs? Perhaps abundance vs scarcity mindsets?

Thanks for the kind words. I helped on the brain rendering side of things but I’m not an expert in the field he he. You seem to be way more knowledgeable than me. Do you have any of your work out there? I would love to check it out.

Is it still your claim that people spending 60k on Cybertruck don’t want it? How do you know? Given the lack evidence feels like motivated thinking. You don’t like Elon and can’t accept that tons of people actually like him and his products.

The motivation to buy something is always because you want it. That a product doesn’t meet your needs or expectations later is a different story. What’s your evidence to claim that people spending 60k in a cybertruck don’t want it? What’s your evidence to make a similar claim or the opposite for any other purchase? Without evidence it feels you are making baseless claims about peoples motivations.

Just quoting the above

“An artificial boost is given to stuff nobody wants, but at a lower price can be convinced to buy”

So people spent 60k on a cybertruck that they didn’t want? Is that the claim?

So people spent 60k on a cybertruck they don’t want? Do you believe that?
