The speed of light is the speed a massless thing *must move at* to make our reality what it is. When looked at with a cosmic perspective, the speed of light is somewhat slow, it can be overwhelmed by a black hole, bent out of shape by gravity, and it takes millennia for it to travel in interstellar space.

We can’t really answer the question very well because the best we can say is ‘there has to be a cosmic limit, and it might as well be ~299.8 million meters per second.
