Plus by that example, computers have always been intelligent considering that they were created to, well, compute things several orders of magnitude faster than even the smartest human can do by hand.
The argument I and others here are making is that what you call "intelligent" is a property that also other tools exhibit which are rarely called "intelligent". You can certainly do that, but that does not prove us wrong (and also doesn't fit what most people would consider "intelligence", as fuzzy as that concept might be).
