It is indeed, but intelligence is pretty unevenly distributed among humans.

It also means more stress on the planet's ecosystems. There are awesome things on earth besides humans, and one of the problems with humans is that too few of us seem to understand this.

In theory. The jury is very much out on whether we can actually do it. Personally, given what has been done to address climate change so far, I'll give long odds against.

More smart people is not the same thing as more people.
There's so much to unpack here, I'd love to have a longer form discussion in a place where we won't run out of thread depth, but I can't dig into all of the points in this format.
This all gets very philosophical, but seriously, optimism is much better than pessimism here.
> There are awesome things on earth besides humans
Like what? Nature is cool, we shouldn't destroy it, but nothing else is truly sentient on this planet besides us. Nothing else on this planet can ponder and understand the world like we can, this is a good thing that the universe should have more of. A meteor (like the one that killed the dinosaurs) could hit this planet at any time, in fact it's pretty likely that it will happen again. And on a long enough timeline, the sun will die and ALL life and ALL nature will die.
In the interim what should we do? Should we just sit around on this planet and wait it out trying to preserve things the way they were when humans first evolved? What's the point?
I prefer to take the humanist approach, I like to think that humans and intelligence will make an incredibly cool, adventure-filled future for the universe and that we can and will do great things with more people.

This is definitionally wrong. Sentient merely means "having sensations" or even the weaker having "senses". Perhaps you mean "sapient", with reasoning, self-knowledge, and an "internal life".
This too would be wrong, but not as obviously so. When we actually try to look and measure other animals fairly, we generally find that in measures of cognitive capability, there are animals that are not that different from humans. Many animals pass the mirror test. There are birds with complex vocal languages. Both apes and birds have been recorded spreading adaptions in food preparation within a cohort and down generations (the two astounding cases are dealing with the toxic backs of cane-toads in Australia -- learning to flip them over and only eat through the stomach (corvids) and picking them up and washing them (ibises)).
You also have the opposite problem, where things we think we're good at, even ones some would say define us as a species, are actually pretty poorly done by many of us. GPT-2, which is clearly not sapient, and only capable of writing a terrible, meandering essay, still does better than many high-school students, or even college students. And we now have much better examples, that still clearly aren't sapient.
Yes, this is what I meant. What I really meant to say was "nothing else is truly sentient on this planet in the same way that humans are."
And to further elaborate what I'm really trying to get at is what Carl Sagan said "we are a way for the cosmos to know itself". No other creature is capable of it in the same way we are.
Yes I understand that consciousness is a continuum and that some species are more sentient than others (humans are obviously the furthest along this continuum though I would say).
Obviously I am biased since I am a human, but I really do think that the human ability internally monologue, to reason about our own thoughts, build complicated mental models and make decisions about them, is unique in the animal kingdom, possibly the universe depending on your parameters to the drake equation.
> nothing else is truly sentient on this planet besides us.
Your optimism is one thing, but this human supremacist stuff is just wrong. Do you think humans are a separate form of life,evolutionarily distinct from the animal kingdom or something?
There's clearly a qualitative difference between humans and our closest relatives. There's some axis on which humans are an outlier for life on earth. I mean, we're not worried about any other animal rising up and taking over, for one.
Some humans are awesome. Other humans not so much.

More smart people is not the same thing as more people.
