My biggest concern with these forks, is do they get the security updates quickly enough as they're all downstream from either Chromium, Firefox, or web-kit. I've tried Zen a bit and had a good experience. From a privacy perspective, cookie management, containers, anti-fingerprinting, and telemetry are probably the biggest categories to address.
Again, I always have security concerns for the forks getting patches quickly. The smaller the team the more risk likely in this category. Librewolf won my vote. I use it for almost everything. If the page won't work there, I typically have to use Chromium because the site is just poorly built.
I'd also recommend doing something to manage privacy at the DNS level for your local network/machine. Piehole or NextDNS would be a good place to start. I landed on NextDNS as it's pretty cheap, easy, and stable. With internet, it has to "just work" or the family gets annoyed fast. I can still black-hole traffic from my network that is phone-home telemetry from devices more concentrated on collecting info for the manufacture than doing what they were purchased to do.
Let’s take the original comment at face value and in earnest for a moment.
Wouldn’t the human race be more like a parasite?
In all honesty, I don’t think the earth needs us, nor would we qualify for a symbiotic relationship. Earth really doesn’t need most of its inhabitants.
That would move to a more existential question of what it means for earth to survive or be “alive”? Support any life?
