Do you find code changes the world in which we organic humans live?
Yes, I do. It will change every single aspect of life - medicine, war, politics, genes, evolution, society (e.g. how you meet friends, how you make families, etc.).
Should algorithms be allowed to decide on philosophical questions of human existence?
They shouldn't, but they will be. Humanity is not mature and wise enough to deal with its own invention. It is like Frankenstein.
The question is: what will remain?
Chaos, lack of freedom, lack of purpose, consumerism
I am not optimistic about it, at all. I hope I am wrong.
I, too think that AI is going to change our lives immensely. So this is a matter to discuss by many many people and in cooperation with governments and companies who have the power to create AI applications.
Look here, an interview between Google and Yuval Noah Harris.
I hope you are wrong. :)
