No, but they said it's an interesting philosophical point to consider, because some bacteria did more damage than us. This isn't true (it's not an interesting point), because we're arguably the only species that know we're causing damage, and can choose not to do it.
I don't think that's the interesting philosophical point. The interesting part is that out of such a devastating event emerged a much more diverse ecosystem that couldn't have existed otherwise.
The timescale is important though. It happened slowly enough that other forms of life could evolve and thrive. We're changing things and killing off species too quickly for evolution. If we screw up geoengineering it could be so fast that we wipe out everything (including ourselves). Maybe some extremophiles will survive at least.

That is quite definitely not how evolution works:
1. Other individual forms of life don't "evolve". Evolution only works by killing off large numbers of creatures, and only ones that have genes that differ by chance, and are more fit in whatever the new environment is, exist to pass their genes to the next generation.
2. There have been a number of significant extinction events that happened in the past that were much faster than whatever humans are doing now. I'm pretty sure the meteor that wiped out the non-avian dinosaurs happened pretty quickly.
Of course they do. Populations can evolve with successive generations without ever killing off large numbers of creatures. They simply do it slowly as conditions change and those with certain genes become advantaged over others and become more common. It's the "passing their genes to the next generation" which becomes a huge problem when everyone in the current generation dies or any creature that is born dies before it can reproduce.

But not faster than what we're capable of doing if we start geoengineering and it all goes wrong. The dinosaur killing meteor took a long time to kill off everything that it did (on a human timescale). How long exactly is uncertain but likely thousands of years to tens if not hundreds of thousands of years. Time enough for a whole lot of generations. We might not have that long if we poison our atmosphere, destroy the ozone layer, or kill everything in the oceans.

I don't know where you're getting this from. Everything I've read was that the large dinosaurs were killed off due to the effects of reduced sunlight in a few years. Here is an article that says it took 15 years: https://phys.org/news/2023-10-asteroid-year-winter-dinosaurs...
While the great oxidation event happened over a prolonged period of time, evidence points to a significant decrease in the size of the earth's biosphere over that time [1]. It's hard to say exactly what happened that early in the earth's history, but if we look at mass extinctions, they are by definition a rapid decrease in biodiversity where evolution fails to keep pace with extinction. If you graph the number of species over time, you see these periodic cliffs when mass extinctions occur [2].
The problem with climate change is not that humans will destroy life on this planet - it will recover from us, eventually - but we can make it much harder for us to live here and cause a lot of suffering and harm, and maybe even cause our own extinction.
I think it’s an interesting philosophical point to consider. In fact, I remember finding researching and writing a paper on this general question fascinating as a philosophy undergrad.
