"If there is no free will, then we are all merely machines. And, if we are all merely machines, then the likelihood that other 'machines' (i.e. machine-learning algorithms and AI) overtake the human race is but a matter of time."
Take a look around :P
"Also, if there is no free will, there is no morality -- how can an individual be held responsible for 'bad actions' when he/she had no choice in the matter? How can Thanos be 'evil' for wanting to annihilate half of all the beings in the universe?"
Morality changes depending on the society one is looking at.
I never really considered Thanos evil... just misguided and lazy.
I know these aren't particularly stimulating well thought out responses, but I'm getting ready for work and a little short on time. My apologies.
I'm not convinced there is or isn't free will,.. I'm just struggling with it. A few years ago I was introduced to the concept that wheat domesticated humanity rather than the other way around and taking that into account with Sagan's theories on genetic drivers and it left me with a lot to sift through, lol. I hope I'll ponder this throughout the day and have a more compelling reply, but I didn't want to get stuck in a loop and just burn out before responding.
