alt Hacker NewsI don’t think we actually care about co2 levels. I think we use them as a proxy for o2 levels (same as our bodies do). So your idea would be great.

This is extremely wrong: CO2 impairment kicks in around 1000 ppm[1] possibly lower.
You can hit this breathing by yourself in an unventilated 3x3m room (literally measured in my house).

I'm pretty sure that in a room where we replaced nitrogen with co2, we would be dead even if O2 concentrations were the same. Something about partial pressure. I notice AI explanations agree with me (not going to copy and paste them).

What makes you think that?

Huh. You don't know that, and are making it up. It's almost certainly false.

Probably. ISTR that depriving a body of oxygen results in a different response than overloading the body on CO2. It's why if you completely displace all air in the room with CO2, people choke, panic, etc, but if you use Nitrogen, people just keel over dead without realising it.
