alt Hacker NewsThe ethical framework is simply this one: what is the worth of doing +1 to everyone, if the very thing you wish didn't exist (because you believe it is destroying the world) benefits x10 more from it?
If bringing fire to a species lights and warms them, but also gives the means and incentives to some members of this species to burn everything for good, you have every ethical freedom to ponder whether you contribute to this fire or not.
I don't think that a 10x estimate is credible. If it was I'd understand the ethical argument being made here, but I'm confident that excluding one person's open source code from training has an infinitesimally small impact on the abilities of the resulting model.
For your fire example, there's a difference between being Prometheus teaching humans to use fire compared to being a random villager who adds a twig to an existing campfire. I'd say the open source contributions example here is more the latter than the former.
