I honestly believe that high intelligence while short term is extremely advantageous, long term it is self-destructive.

I like to imagine there are countless planets with perfect ecosystems of living organisms where no single species dominates whole planet.

I'm curious what makes you think that. That is, of course, one of the general solutions put forth to the fermi paradox. Ie either the species develops species killing weapons (like nukes) or individuals gain massively destructive weapons. But I find these things unlikely. Even exploding all of our existing nukes in the most devastating locations would not destroy humanity or the earth. We'd bounce back - tho if such an event is inevitable, perhaps we would ride an endless wax and wane between devastating destruction events every 1000 years.

There is no such thing as a perfect ecosystem because we live in an imperfect universe, this is if you look at any significant timescale. Eventually you're going to get hit by an asteroid or a gamma ray burst, or some mega volcano is going to pop and cause world wide levels of destruction. And generally we see some reestablishment species is going to dominate for some time.
