Preventing painters from painting and letting these exact art-depraved artists express their opinions on things is a bad idea. That's Literally Hitler's origin story.
"Computers are useless, they can only give you answers." - also Picasso.
But he was an artist. Technology was just a tool for him to make art, nothing more. I'm sure if you'd shown him an iPad with a modern sketching program on it hooked up to a dye-sub printer, he would have been at least a little intrigued. He might have disregarded it as a toy, but he also might have worked with a new medium to see what he could do.
The moon landing was 1969, less than four years before Picasso would die at the age of 91.
I'm absolutely not surprised that he didn't care, I don't think the actual consequences / effects of the moon landing would have been readily available for Picasso to grasp (or many other people at the time).
Plus, at that age, nobody gives a fuck about anything anyway.
I don't, and i don't really care nor mind what he think, and that's the point. I don't care what he think, i don't care what he feels about the moon landing, heck, i don't really care about what you think about him, because i can let people have their own opinion instead of trying to gatekeep thought.
You know what a narcissist will do when asked about moonlanding where they don't really care? They will agree that it's the greatest achievement of all time despite not care a bit, because narcissist will insert themselves and their opinion into everything.
