I tend to agree, however with the universe being so vast and the number of planets out there simply impossible to comprehend I always end up thinking "that sounds far-fetched but it almost certainly happens somewhere in the universe".

Now of course if we consider the much, much smaller subset of planets we may hope to actually observe then of course it might not be so likely.

I also think the initial point of the article in insightful, although rather obvious: since the planets we're currently looking for are not Earth-like (because we're currently unable to detect planets such as Earth in other solar systems) it means that if we find something it'll probably be very different than what we're used to. Now of course the author goes on to flip that around by saying "since we're looking for planets that are not like earth we're going to find this and that" which is obviously a bit presumptuous. Still, fantasizing about alien worlds is something I always greatly enjoy so I'll allow it.
