Wikipedia ***IS*** monitored for accuracy! Perhaps by MILLIONS! SO WHAT???? They're not perfect, not necessarily smart, not working full time, etc... AND, even if they were perfect, the sheer size makes such a feat IMPOSSIBLE to do 100% and still keep the ideal in mind.
There IS, after all, a reason why it wasn't done earlier.
NOW, as for computers taking over the world????
1. They CAN'T do it! Even if they had the wisdom, etc... even if they could communicate with the robots and vehicles and cameras, visual control is limited.
2. They CAN'T do it! Even if they could see so well, they don't know what they see.
3. They CAN'T do it! Even if they know what they see, they don't have the wisdom.
4. They CAN'T do it! Even if they had wisdom, idiots like Bill Gates would make sure they couldn't for long!
Despite all the hype you hear, and shows like wargames, even the fastest biggest most expensive supercomputer ever made is NO smarter than your watch! FASTER? YES! More memory? YES! More flexible? YES! Smarter? NO WAY!! !!
BTW I don't know how fast computers will get, but Intel, for example, is ALREADY using nearly every trick anyone has ever come up with. Many are DECADES old, and were abandoned earlier because they found out how to push the technology to its limit. That technique was exhausted in the mid 1980s, so they are back to the tricks. This means it is getting harder to just turn up the clock speed, etc... to make processors faster.
