Dang. I just can’t choose. I would like to communicate with so many.
‘Dogs’ is a tempting response, but I feel like I’d be disappointed and a little disturbed by how slavish we’ve made them. Cats… would probably tell you to fuck off and stop bothering them.
Octopodes and whales I think would make for a very interesting conversation. The octopus is, imo, the closest thing we have to an alien on earth. Iirc their intelligence developed on a completely different pathway to mammals; imo if they didn’t die so quickly they’d be as likely to have become dominant as us smart apes.
A conversation with a virus would be very boring imo. They don’t have a mind, would probably just repeat “REPRODUCTION INEVITABLE, RESISTANCE FUTILE” over and over.
