It's really not at these scales. Earth and Mars go from roughly 4 light minutes apart to over 20.
At the best case, saying something and then waiting 8 minutes for a response is hardly what I'd call "real time".
Speed of light is insanely slow at the cosmic scale.
No, it's not slow, at all. It's the speed of light.
Unfortunately for us humans, we are a relatively fast form of life, when compared against the scale of our solar system, much less our galaxy, even when communicating at the speed of light.
It's the fastest speed information can go through space, as far as we know. Unfortunately, there's a lot of space. And a mean a LOT.
