The practical bottleneck for most AI tooling isn't model capability anymore - it's the orchestration layer. Getting reliable behavior across edge cases requires more engineering than people expect from demos.
The bottleneck might be the air in the room

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).
EDIT: ignore this; I was confused / misinformed It's about pH. CO2 creates carbonic acid when it dissolves in water. Your blood pH, in turn, controls how much you feel like you need to breathe. So with high CO2, your respiration rate slows down, and that can lead to low oxygen levels. Note that the physiology and biochemistry of this is complicated (e.g. blood is a very good pH buffer and it's actively regulated by k…
Wouldn't high CO2 make you breath faster?
Re: The bottleneck might be the air in the room
#233A bit OT, but was anyone else amazed by the bad UX of that CO2 monitor in the picture? If you notice, that monitor has a "traffic light" gauge at the bottom to tell you if the current CO2 level is critical. That traffic light is currently showing RED, i.e. highly critical. The thing is essentially sounding the alarm and prompting immediate action. However, became the traffic light colors are printed on and static and…
These CO2 monitors have a configurable audio alarm. The present model uses an e-ink display to conserve battery. Physical LEDs would also work, but really in practice you don’t look at the unit and instead are notified by the audio alarm.
Re: The bottleneck might be the air in the room
#234I've noticed that cooking with gas is easily the worst thing for CO2 levels. Even with lots of ventilation my kitchen will hover around 1200ppm until it's over with.
I swear I can feel the 430ppm already. I was born into a world with 340ppm. I can't imagine what it's going to be like when we hit 500+ globally.
I'm in the market for an active CO2 scrubbing solution that I could deploy at home. Scrubbing the entire planet won't work but I could make a small room feel like 1960 again.

Ah, that makes more sense.

#236LLM prose really sucks the air out of a room.

#237My employer started using CO2 monitors in meeting rooms 15 years ago, it’s really a useful thing to have. As well as the meeting rooms having windows you can open.

if you just want to know if CO2 is too much, 300ppm precision is fine. I dont need to know the exact level, just give me a green/yellow/red LED and make it cheap so I can have a sensor in every room
No, it's not. You generally want to ventilate an office when you reach 1000ppm, but then the IKEA will often warn you already at 700ppm. 700ppm is fine.
You generally want to ventilate almost continuously, so if a circulation fan kicks on at 700 instead of 1000 that's really not a big deal.

I can just imagine the horrors and skin crawls that your last sentence has evoked in some people's minds. Not the state!! But seriously, so much care needs to be taken here. OK, well "care" at least. Employers certainly would benefit from scrubbing CO2 from the air, in terms of productivity. I'm willing to bet that with central air it would be quite easy, and even with heat and AC off, lots of places still circulate…
In practice, one would use energy recovery ventilation to exchange air with outside rather than a CO2 scrubber (not clear if you actually meant a scrubber). The place to look is existing codes for ventilation. Exempli gratia: https://dos.ny.gov/system/files/documents/2020/09/2020-mcnys... (see PDF page 46). Regulations to enforce outside air being brought into human spaces already exist. I have been in some office bu…
I should have said it more clearly, I just thought HN would take this stance regardless. If you tell an employer to ensure CO2 levels, and it shows an improvement in productivity, employers may think "Hmm. Let's improve this further!" and add O2 as well.
In terms of outside air, a lot of US cities I think would not benefit from that, all that much. Especially during certain parts of the day, with a lot of smog.
But regardless, all that entered my mind was "Once employers are required to add any form of scrubbing, and perhaps O2 injection, they'll over do it for optimal employee output." Regardless of whether it's helpful once the employee leaves the workplace.
I'm not against this, I'm just actually saying the regulation should be locally defined.
