That was an interesting read, but its logic seems a bit contradictory.

On the one hand it figures the aliens would be so technologically advanced that any resistance would be futile (and, as a side note, of course we couldn't fight Matrix-style; that would be a battle against self-aware machines we created, not an alien species ).

Yet it posits we'd be the ones that would have to establish the means to communicate.

Realistically, all of the underlying assumptions around intelligent alien life would mean that the likelihood of our civilization being the first they've encountered extremely low. And even if it was, the idea that such a race wouldn't have a protocol (or come up with one prior to first contact) for establishing communications with an alien (to them) race, that they'd just show up and look at each other saying "shoot, now what do we do" seems incredibly unlikely, assuming they have an actual desire to communicate with us.

And if they don't want to talk to start with, us making little models of triangles likely won't change their mind .
