  • Pulse oximeters do not directly read oxygen. They use light absorption to approximate how much hemoglobin is oxygenated or deoxygenated. The de/oxygenation changes the light absorption (its why arterial blood is bright red and venous blood is darker). That is then converted by mathematical algorithm to a estimate of oxygenation the “reading”.

    This is stating essentially that in black skinned people the changes in light absorption because of the skin color results in the algorithm giving a falsely higher reading than is actually present in the patient.

    The math will have to be fixed in some way for black people to receive appropriate care. Whether that is a device unaffected by skin color or different math based on skin color needs to be figured out.


  • For private companies they can do whatever the ceo/owners believe will make money.

    At the C-suite level there are a lot of people who are misinformed about AI because of media reporting and a couple positive interactions. Because private or not their circle includes the ones pushing AI. More work done, less effort sounds great if you haven’t yet realized consequences of work quality dropping much less the longer-term loss of a younger generation that never gets trained or makes money to buy product.

    There is already a severe economic issue wherein products simply aren’t made for the bottom 70-90% of the population. A majority of buying/selling has been over decades focusing to an upper range of earners. Its why the average new car is now nearly 50K while median wage is 62k/y.


  • The standard is bad parents, hatred for society and school (honestly normal for many teens/adolescents, esp if bullied), echo chambers that reinforce the hatred (abnormal), easy access to guns (abnormal but often concurrent with bad parents and ofc the US).

    This is of course an oversimplification and not every shooter has all of these but there’s been more than enough occurences by this point to know what the majority “reasons” are. The two ways for society to fix this would be to make gun ownership more difficult, and to have parents positively involved with their children.

    Republicans dont want to do anything to limit guns until its the “other side” that has them see the lack of anything in the multiple events since Columbine including Uvalde vs Regan as CA governor and Black Panthers having AKs. And in our stage of capitalism the companies do not care about parents spending time with their kids and the unions are weak (though theres been some recent limited improvements there).




  • I mean you get screwed on one side of the equation anyway just because of sunlight hours shortening by the season. Hell, Alaskans have months without meaningful sunlight. And then months with basically 24h sunlight. Unless jobs were to adjust their hours with the seasons theres no way not to get screwed at some point.

    There’s an appreciable increase in cardiovascular events and car accidents when we lose an hour. For that reason alone we should stop the stupid clock changing.
