Super Intelligence would expand at near the speed of light, reaching us extremely fast. It would be unlikely for the window of time that we have telescopes and the window that the aliens are expanding towards us to overlap.

Interesting that your model allows for super-intelligence but not faster than light travel.

I mean one of these is consistent with the known laws of physics and the other isn't. Seems reasonable to me.

Different. Super-intelligence is a plausibly reachable thing, a question of engineering. TIL is an uncertain thing, requires entirely new physics, and completely unknown tech.

Isn't that just "physics"?
