I was thinking the same thing. Those locust plagues are hugely devastating...

Thinking beyond the snark for a bit, though, locusts might be an example of a species-level cancer cheating the “rules” of a habitat.

Humans? We just throw the rules away altogether and have historically written new ones that only apply to us. The difference between us and locusts, though, is that many of us fight back against our own short term interests and argue “hey, we’re a tumor right now. We should consider not being one of those.”

There's an important difference between a tumor and an organism: one can sustain itself, the other is a parasite. So what would obviously put humans over the line? Establishing self-sufficient colonies off Earth seems to be beyond the reach of any swarm of locusts, but possibly viable in a 1000-2000 year timespan for people.

Ignoring timescale, modeling a single tumor as a parasite of humans seems the same as modeling humanity as parasites of nature/world/universe.

And if nature/world/universe was sentient, it would be angry at us and it would want to fight us. And if tumors were sentient, they would assert their rights to live and write their own rules.

Alas, we're the only sentient beings in this comparison, which makes tumors bad and universe a resource, by our standards - i.e. the only ones that matter.

Agreed. What can society, which creates corporations, do to limit the likelihood that they will "go rogue" to harm society?

Regulate them, limit them and in extreme cases kill them. And the thought that corporations are cancers of human societies that cheat is not a new.

Corporations are more multicellular organisms than cancer. They are capable of achieving far more than a single cell or person, for better or for worse.

I think the person you are responding to is alluding to humans, not corporations.

Only under certain circumstances. It's not inevitable that we be this way. Our most powerful societies cultivate a condition where our economic activity is this way.
