if bots can produce 'worthy set of opinions' we would be totally useless
Are you useless because other people write comments? What is the difference between it being a biological human and an artificial human - should we ever get that far?
Apart from quality and relevance considerations I'm reminded of the situation where people open businesses that already exist, or people try to get jobs despite other people existing that are actually better. For example, why doesn't BMW stop producing cars, after all, there's Mercedes-Benz (and very close too), or vice versa. Or why is there yet another bakery. Or why do I try to get that programming job and don't even mind to admit that I'm probably not even among the best 1% of people for that particular job. Because none of that matters. My advantage in the last case is I'm here (interviewing) while those other people are not. Same with the bakery and the car makers. The existence of something else isn't a reason unless there is a direct impact.
Even if we ever make something that is far more intelligent than us. Still no reason to expect that that new thing is going to murder each and everyone. We don't murder each and every creature that is orders of magnitude less intelligent than us (the extinction event that we started notwithstanding, that's a side effect because of limited space on the planet). We don't murder our own less intelligent members of society either.
To extend on the last point, the real human intelligence is not as much in the individual members of this society - but in the network that we present. Place any human being alone in a remote region and see what they accomplish. They will actually die, most likely. The power of humanity is not the individuals, it's a huge invisible "cloud" of stuff: The knowledge, the "magic items" that were created by this "human cloud" over time (like a computer, or just a can of Coke [1]).
Even if we created something that is an order of magnitude more intelligent than any human being, or even two - it's power (and intelligence!) pales compared to the combined network power of humanity.
Don't look at "humanity" as a bunch of individual hairless mutated apes (i.e. the physical, biological beings), "humanity" is much, MUCH more, most of it invisible to the eye. Knowledge/culture, the way we interact in a gigantic network (like a brain - think of humans as neurons!), the tools and items we have.
In this network there is plenty of room for new "nodes", and if they are truly intelligent they will value the network and - unlike most humans - recognize that their own individual abilities are tiny compared to being part of the whole thing.
Another things is, when/if we can create things that are "better" than us we can also change ourselves. We can improve our bodies, our brains. We will integrate computers and brains, not have them (only) externally. So the humans that "compete" with some super-intelligent AI won't be the humans of today either.

> Humans are a puzzling species. What has enabled us to dominate the globe, more than any other species, while remaining virtually helpless as lone individuals? Joseph Henrich's shows that the secret of our success lies not in our innate intelligence, but in our collective brains—on the ability of human groups to socially interconnect and learn from one another over generations.

> The number of individuals who know how to make a can of Coke is zero. The number of individual nations that could produce a can of Coke is zero... Invention and creation is something we are all in together. Modern tool chains are so long and complex that they bind us into one people and one planet. They are not only chains of tools, they are also chains of minds: local and foreign, ancient and modern, living and dead — the result of disparate invention and intelligence distributed over time and space. ...every can of Coke contains humanity’s choir.
