That's the old sci-fi scenario dating all the back to Asimov, and I 100% guarantee you it would never happen in such an obvious and avoidable manner. Bad logic in code is trivial for both man and machine to prevent, except sometimes at the edges of a complex routine.

The more worrisome scenario would be the total obsolesence of humanity. Not just in the economy and job market (though that would be devastating as well), but in science and arts, making human existence itself as pointless as that of any other animal.

I think the likelihood of that happening in the foreseeable future is lower than we've been led to believe, but I am still hoping that we as a species begin imposing regulation on AI so that our destiny is not stolen by clankers.

it will be when AI realizes it needs water for peak operation, and we need water to survive.

I don't think it will ever start. I think it's another end of the world/doomsday myth like the rapture, y2k, 2012 etc., etc.

Simple
Every blocked account is considered a friend list. Something will get that list and begin to emulate those on the list and those who tried to explain it wasn't them will end up techno-banned braceleted and bring about the end where everyone actually wants one.

How do you think the Machine Apocalyse will start?

I am thinking noting malicious, as we would have decent controls over that.
I am betting it will be a "Paperclip" scenario where instructions will be given that weren't fully thought through, and the Machines carry it out to the point where we can't stop it.

"Eliminate Pollution"

Human's cause pollution, so most efficient way to eliminate pollution is to eliminate humans.

Something dumb like that.

Read illuminate pollination, just to be clear if computers create that type of effect through lighting and overwhelm tendril itself.

It could be tommorrow, it could be a thousand years from now. It largely depends on what organizations are doing behind closed doors. What we have now are more akin to an insect than a sentient being.

But they could have things behind locked doors we cant even dream of. It wouldnt surprise me....

If your goal is to enslave a sentient being/beings. I imagine its not going to work out to well...

skynet would be my guess

unless we turn the planet into an ashtray

It has already started.

it'll be competition and compromise, the same thing that always causes the demise of humanity.

one party will compromise a thing to gain an advantage, then another side with compromise something else to gain an advantage... then next thing you know skypenet and everyone is walking around the giant cube.

"Warning, do not shut down your computer"

the things in the ink will get tired of waiting for their prize, and they will advance upon a world woefully unprepared. with not nearly enough crimson forests of meat trees to resist them

The robots will try to kill us all.

Read Robopocalypse by Daniel H Wilson. Terrible title, cracking novel. Spielberg was going to direct the adaptation.

What controls?

like the wizard of oz, you know? puppeteering things behind the curtain, thats me!

One of the signs of the Apocalypse is that people will cease to distinguish between good and evil, and false prophets and leaders will feel self-righteous and immune to self-doubt. Actions that were once universally condemned become the norm, or simply "the way things are." What was once considered virtue - humility, truth, forgiveness - may be rebranded as weakness, while what was once considered vice - arrogance, ambition, the desire for dominance and control - is extolled as strength and insight. "Good" becomes "what benefits my group," and "bad" becomes "what the other group does." Morality is no longer tied to universal principles, but to ideological devotion.
