This shouldn't come as a surprise, since UFO fanatics already are convinced that we are not alone in this multiverse.

So he implies the anomaly could be an advanced type 2 alien structure?
Not Kurzweil himself on this particular issue (that I know of), but this is clearly the implication of the article and paper. The paper suggested structures to capture solar power, and that is in line with these other theories. The paper cited here is banking on a "cloud of comets" as the reason for these "energy dips." It's not surprising they would not suggest anything technological, which is nowhere near proven.
Edit to add: It's 1481 light years from us.
Our most promising theory invokes a family of exocomets. One way we imagine such a barrage of comets could be triggered is by the passage of a field star through the system. And, in fact, as discussed above, there is a small star nearby (~ 1000 AU; Section 2.3) which, if moving near to KIC 8462852, but not bound to it, could trigger a barrage of bodies into the vicinity of the host star. On the other hand, if the companion star is bound, it could be pumping up comet eccentricities through the Kozai mechanism. Measuring the motion/orbit of the companion star with respect to KIC 8462852 would be telling in whether or not it is associated, and we would then be able to put stricter predictions on the timescale and repeatability of comet showers based on bound or unbound star-comet perturbing models. Finally, comets would release gas (as well as dust), and sensitive observations to detect this gas would also test this hypothesis.
At this separation, the second star cannot currently be physically affecting the behavior of the Kepler target star, though could be affecting bodies in orbit around it via long term perturbations. If such a star is unbound from KIC 8462852, but traveling through the system perpendicular to our line of sight, it would take only 400 years to double its separation if traveling at 10 km sec⁻¹. So, the passage would be relatively short-lived in astronomical terms.
The last idea the astronomers looked at was a series of comets orbiting the star. These could be surrounded by clouds of gas and other material that could produce the dips seen. The lack of IR is puzzling in that case, but not too damning. If another star happened to pass nearby, then its gravity could disturb the first star’s Oort cloud, the region billions of kilometers out where we think most (if not all) stars have billions of icy objects. This disturbance could send these ice chunks flying down toward the star, where they could break up, creating all those weird dips—ices in them would heat up, blow off as a gas, and could explain the odd shapes of the dips detected, too.
And, as it happens, there is another star pretty close to KIC 8462852; a small red dwarf about 130 billion kilometers out. That’s close enough to affect the Oort cloud.
This doesn’t close the case, though. Comets are a good guess, but it’s hard to imagine a scenario where they could completely block 22 percent of the light from a star; that’s a huge amount. Really huge.

This is great! I really hope it turns out to be the vulcans or something. Not the comet cloud the paper hypothesizes it to be.
If everyone knew, without a shadow of doubt there is another intelligent species within our galaxy, just imagine the good it could possibly do. Maybe we'd take the trillions spent on fighting each other, and put it all towards more exploration of space. Heck, it's what we should already be doing...
