Communication requires both input and output channels. All of the instances I can think of from the animal world involve a sense (hearing, sight, smell, touch) which has evolved with a different benefit. Then an output can evolve to take communicate using this sense as the input.
This seems orders of magnitude less complex than evolving input and output simultaneously which would be required for direct brain communication (a least I can’t think of another option).
Even if it could potentially happen, before it did there would be many instances of indirect communication evolving. Take-off happening first in a species with indirect communication is a fairly inevitable consequence of the relative complexity of the evolutions required.

I’ve wondered in the past where Electroreception, or something could evolve in this direction.
