A loose estimation, shows that if an intelligent algorithm, manage it to occupy just 1% of the net, he can get grip on 160000000 Gigabyte information processing. If this algorithm act as singular Hive mid it would be the most dangerous entity humanity ever face.

Bit-coins wealth farming already uses Technics who connect multiple computers over the world to run one program.
I EVEN didnt integrate server-farms.

This entity would be as smart as 160.000 humans unified in one single mind.

This is one single parasitic algorithm occupying 1% of all home-computers, with out even touching a server farm.
