1. AI has not mastered games.
I can only speak about dota, but what they basically do is enforce rules that make it possible in the first place to create an AI.
AI did not play real dota, is was a caricature of the real game and even then people did beat it on the first day just by outsmarting it, some pros have beaten it "fairly", too.
It's just a PR stunt.
And here you are dreaming about Singularity. GIGAKEK
2. 3d printing is still dogshit. Most overhyped technology of the last ten years. All it is really good for right now is fast-prototyping.
In the medical field no major breakthroughs have been made either, the only thing that's done at the moment is printing frameworks for cells to grow on, has absolutely nothing to do with printing "living tissue".
3. you're a retard for doing this. you're even more of a retard for propagating this. just because some pseudo treatment has worked for you doesn't mean it will work for others. No one understand how the brain really works and you go around telling people to get shock treated, these shit threads are really getting on my nerves.
4. that's the only point I agree on. Humanity has been at the brink of nuclear war many times,
the most noteworthy example is this

if an ai was in charge of the retaliation instead of a human it would have just shot.
WW 3 will be started by a machine 100%.
