How a Technological Singularity could be problematic

If it is a large robot or even an airborne drone both of these could be dispatched simply by an RPG (rocket propelled Grenade) on the ground or a missile from a jet fighter in the air.

However, this wouldn't be a problem singularity wise unless you had maybe thousands of Predator Drones attacking any single country or something like that all at the same time and starting a human war.

No. The most problematic way I can see would come from a worm within the Internet itself that burrows it's way into every connected home computer on earth including universities and government computers and military computers.

Then one day this intelligent worm decides (for one reason or another) that human beings are interfering with it's survival.

So, what would it do?

Likely find a way to poison water throughout the U.S. which might kill hundreds or thousands of people in different areas before people found out that something was definitely wrong.

It also might poison or tamper with food where the food was being automatically processed in various places in the world.

If a worm kept doing stuff like this at random which could not be directly traced to any human being or government (because no government or company authorized any of this) it might not be caught doing stuff like this for months.

Meanwhile, all sorts of people would be dead at random around the world. However, no human being would be directly responsible for this (even though one or more programmers wrote this worm which could have been programmed by any government or criminal group worldwide). However, the intent of a worm like this likely wasn't to kill mankind so this was the worm's idea of self preservation rather than the will of any single person or group on earth.

So, this is the Technological singularity that I worry about the most because 1 or 100 or even 1000 military drones with Hellfire missiles might be shot down before too many people are killed.

However, a worm that sucks up memory from people who leave their computers online (there are a lot of these) especially PS3's which can be run in a series worldwide if they are run online. In fact, one of the biggest supercomputers ever built was only a series of PS3s all connected.
