Who are you to speak on behalf of society? Wouldn't society also be better off if those who stole your car got caught?

Further, I'm not sure why there is an expectation of privacy in public places. You don't have to consent to being filmed when you're walking down a public sidewalk.


You should.


Why?


Anyone who thinks modern data centers don’t use recirculated water can safely have their opinions summarily discarded.


Data centers consume...a lot...of water by design, recirculated water, does not means no water consumption. Water must be continuously added in evaporative cooling systems used by many data centers.

[1] - Cooling towers reject heat through evaporation, which uses water, not just recirculates it. Evaporated water is lost to the atmosphere and must be replaced with "make-up" water. As a result, recirculating cooling loops still require new water input to make up evaporation and blowdown losses.

..so outlaw cooling towers and use dry coolers.. what?


Anyone who thinks that modern data centers don't evaporate their "recirculated FRESH water" straight into the ocean can safely have their opinions summarily discarded.


Please google "datacenter evaporative cooling" and then re-evaluate


Whoa: is this the only possible form of cooling?

What if there were a cooler that somehow didn't evaporate water, you might even call it a "dry cooler" - that would be a sweet invention. This might even be required in areas where adiabatic cooling isn't effective (humid climates)!


Even if the ambient relative humidity is near 100%, water's latent heat of vaporization is nothing to shake a stick at.

I like the idea of a giant heat pump into the ground, but heat exchangers are expensive and so is digging.


Nobody is talking about a giant ground-exchange heat pump: liquid-to-air dry coolers exist and are used everywhere. Adiabatic cooling is just cheaper.


Use rectangle and this will never be a problem for you.

Insurance is negative NPV. Trying to make it NPV neutral by giving people tools to self-insure. Starting with an app that lets you self-insure your phone with friends and family.

This is cool. I'm interested in reading more on this concept. Any chance you have a write up of experiences so far? Or can you point to other resources?


This is interesting, it this an experiment or planning to make it real? What markets is it targeting?


It’s real, my friends and I all pay premiums every month, we’ve put aside $1100 so far. Work on it nights and weekends with one of my fellow policy holders. Feedback would be super appreciated.


Interesting approach. How would you make money?


Love this, signing my family up now. Absolutely hate apple care


I don't want to track any of this myself. I want to walk into a gym, have some cameras follow me around, and have it analyze what I did while I was there, including statistics over time.


Wow I really do not want this…cameras to track you in a gym? What kind of dystopia is that?


To be fair, the cameras are already there. This would just make them more useful I guess?


Well if I had to do this, I'd build the whole system just procrastinating walking into the gym :P


Love 4.


I'd be wary about 4. I've worked at a fintech startup before where the founders boasted about how they had moved all their net worth onto the platform. Some time later over a casual chat and drinks, it turned out this was far from the truth. Don't just take people's word for it, I may be biased about startups now, but "trust but verify" is a good motto to go by.


Number 4 makes it sound like a scam to me.

"Don't worry bro, you can trust me" type of vibe.


Growthbook wrote a short paper on how they evaluate test results continuously.

Just to answer some questions I'm seeing from other comments, this is built with three.js. Think of it as a 3d scene with an image rendered on a 2d plane and the camera has certain gaussian blur applied to a section of it. He's using orbit controls for the zoom in/out and for the ability to pivot the image.


I'd be upset if my bank used my checking account to fund Alzheimer's research.


Government does it all the time ;)


And that's a good thing.
