Earlier quoted context omitted.
We already have plenty of those computers. For example, Google computers are able to process the amount of information no human can possibly process during their lifetime. Other computers can help with design or optimization problems that are so complex that no human can perform them in any reasonable time. Does it mean that those computers are more intelligent than humans?
They aren't intelligent by any reasonable definition. Just ask them what color the sky is.
"A computer that is thousands of times more intelligent than humans, means it can do things we might think are impossible. Come up with solutions to problems we would never think of in our lifetimes. Manage levels of complexity no human could deal with."
Or did you just redefine intelligence as: "the ability to tell what color the sky is?"
