Aw, that's nice of pg to want something better for his friend. As cynical as we are about technology, new developments can be so fantastic for accessibility and better quality of life.
You are talking about cobalt and that is only used in lithium ion batteries. You can avoid cobalt by using lithium iron phosphate batteries.
There are active efforts to develop new lithium ion chemistries to avoid cobalt and there are even commercial sodium ion batteries now.
You bring this in to a completely irrelevant conversation, what have you done to help solve it?
Sure I use lithium ion batteries too, in the developed country I live in, I can't go and live in a cave. But I won't buy a SUV that weighs 2 tons to sit alone in it most of the time and have it parked 95% of the time in a garage.
The "what have you done" attack is a bit too easy and, really, this is not about me.
We should strive to be sober, to buy repairable goods whenever possible, to educate ourselves on environmental impact of things, and perhaps more importantly to teach this to our children.

What are you even talking about? This whole thread is about eye tracking.

Are you doing that?
The entire supply chain and lifecycle of a product should be evaluated to understand if it is a net positive or a net negative. Not only the finished product: "wow eye tracking how cool let's deploy everywhere regardless of how the materials for that tech are mined and how the device will be recycled once obsolete".
