You're able to use a search ...

You're able to use a search engine, like Google or Bing or whatever. But those engines don't understand anything about pages that they give you; they essentially index the pages based on the words that you're searching, and then they intersect that with the words in your query, and they use some tricks to figure out which pages are more important than others. But they don't understand anything.

When people talk about the singularity, when people talk about superintelligent AI, they're not talking about sentience or consciousness. They're talking about superhuman ability to make high-quality decisions.

What AI could do is essentially be a power tool that magnifies human intelligence and gives us the ability to move our civilization forward. It might be curing disease, it might be eliminating poverty. Certainly it should include preventing environmental catastrophe. If AI could be instrumental to all those things, then I would feel it was worthwhile.

You have a very precisely defined goal and you build a machine that's superhuman in its capabilities for achieving goals. If it turns out that the subsequent behavior of the robot in achieving that goal was not what you want, you have a real problem.

The robot is not going to want to be switched off because you've given it a goal to achieve and being switched off is a way of failing - so it will do its best not to be switched off. That's a story that isn't made clear in most movies but it I think is a real issue.
