Comment Re:Battery Life, Sleep, Stability (Score 1) 147

15+ hours is the realm of battery anxiety, not a legitimate user requirement. The real acid test is can you get through the work day, and can you get from one airport to another.

Not quite. The real acid test is whether, once you get to your destination, you can do a full workday without waiting six hours to recharge.

Conversely, my Mac's ~14-hour battery life means I've never left the house with the (bulky) power adapter unless I'm traveling overnight.

That'd be fine for the people who live downtown, but you're forgetting about all the commuters.

That's probably a long way off, too. Right now, robotaxis are only allowed on a limited range of public roads, which doesn't include highways (and by extension, bridges and tunnels). So while they might be useful to get you from your home in a city neighborhood to downtown, but not much more than that.

(Also, I doubt anybody's really going to pay for robotaxis for a daily commute. Most people buy cars or take the train for that.)

ignoring the warning that they should be ready to take over at any time if the computer acts inappropriately.

Oh, and there's no such warning. When you get into the backseat of a robotaxi, it won't even start moving until everybody is wearing their seatbelts. I hardly see any passenger leaping into the front seat and grabbing the controls in a traffic incident.

With the exception of the occasional spectacular failure that makes the news (and refuelling/recharging stops), this is already possible. Not legal, but the technology is there.

Nah. I've rode a couple of robotaxis around the city, and while the ride is nice, it's clear we're nowhere near "get in a car and go to sleep." For one thing, the vehicles aren't even allowed on highways yet. And they require months of training on any particular urban area before they can perform reliably. I don't think there's been any training in rural or even suburban environments, which have different challenges. What you say may eventually be possible, but we're still a long way off.

I suspect that would be difficult to do. Many people in poor countries probably either never get treated or don't have any kind of measurable records of their treatments, especially for long-term chronic illnesses like cancer. And then, which countries would you measure and compare? I'd suspect people living in countries that have experienced recent war or environmental crises would have a much higher instance of cancer than those that haven't.

At the end of the day, the only simple comparison to make is between different eras of a country that has remained mostly stable and consistent throughout, like the U.S.

My first guess would be antibacterial soap causing weaker immune systems from lack of exposure, coupled with excessively sanitary conditions leading to inadequate bacterial diversity.

Nah. Even if you wash every single bacterium off your hands, they'll be covered again within a few minutes. And unless you wash your face every time you wash your hands, your face is covered with bacteria, mites, and all kinds of things. Got a beard? Even better. The real problem with antimicrobial soaps is that the chemicals used to kill the bacteria can be retained in tissues and potentially cause various types of human disease.

And I'm not sure what you mean by cleaning causing "inadequate bacterial diversity." Even hospitals, which actively try to sterilize their environments (as opposed to just wiping off the kitchen countertop) are rife with bacteria, including strains that occur nowhere else but in hospitals.

And some forms of cancer use a bacteria-rich biofilm [nih.gov] to help it evade the immune system.

I don't think you're reading that paper correctly. It says that biofilms may potentially play roles in the initiation and promotion (growth) of tumors, but that's not the same as saying cancer cells "use" biofilms. It's more likely that the inflammation caused by the presence of biofilms can lead to cancer.
