Um, I think you're mistaking species with kingdom.

"Birds" are not a species, "mammals" are not a species. I don't think viruses are even described in terms of species because they don't reproduce sexually. I think you'll find that when you actually consider species, most of my points hold.

Various species have methods of communicating, from bees dancing to each other to whales having distinct regional dialects. Yes, humans have added some complexity to it by introducing technology, but that's realy what it comes down to. Technology.

Yes, many species have some rudimentary way of communicating some kinds of information. But obviously bee dances don't compare to any human language, of which there are literally hundreds. A bee for instance has no way to express appreciation or derision for the English language. My whole point here was that humans, on hundreds of distinct occasions, developed languages capable of conveying complex ideas. No other species has developed a language half as capable as any of ours.

Rather than picking the rest of that post apart, I'm just going to stop here. It's pretty self evident that humans are impressive as hell. Denying that is... pretty dumb, and purely rhetorical.

As a side note, don't get too excited about fusion, it's largely a dead end. I expect it will only be really useful in niche applications (like spacecraft). It will be far more expensive than nuclear fision and not really offer any benefits besides abundance of fuel. There's still a huge radioactive waste problem. On the other hand, the sun provides all the energy we'll ever need, and we're getting better at collecting it. I'm really not concerned about increasing energy demands.
