And My Comment:

To begin with: the fact, that we cannot fathom how to do something now, does not mean, that we shall never be able to do it. 300 years ago, no one could have imagined how to make a heavy machine fly, and were thus certain it's impossible - but today, airplanes are a mundane everyday part of normal life. I'm now commenting to a video showing you talking on the other side of the Planet two months ago, using a mobile telephone, and you, many thousands of kilometers away from me, on a different continent(!), shall see this comment instantly if you just happen to be online right now; can you imagine, what such a combination of events and possibilities would look like to a 17th century Scientist??

The fact that today we have not been able to locate gravitons yet does actually bear no meaning as to the possibility that our descendants might someday use them everywhere at will.

And, now, as for what we can already build now = once humanity shall decide it needs it, it shall build it. Thus far, it just didn't seem important enough for humanity to actually taking the trouble to build it. That's all there is to it.
