Is it really that simple? Is society really that dumb?

Why are people so infuriated by Flock cameras but just completely shrug at this (much worse) TV thing? Nothing is going to change until people are that enraged by it.

Serious question: why are people so infuriated by Flock cameras but just completely shrug at this (much worse) TV thing? I want the public to get upset about this. Also, can anyone articulate exactly what data the TV is scraping about your

The paper shows 2024 brains are worse than 2016 brains. Why? It’s not that long, and it’s not like the decade prior to 2016 had less plastics.

The report linked is concerned with more of the auditing side of the industry, which often claims to guarantee 100% brand safe placement. But which obviously does no such thing.

The most plausible reason they might need to dig them up is to remediate them. Landfills require maintenance in perpetuity, which costs a considerable amount of money. The biggest expense is maintaining the top cap—if it leaks, big problems

The most frustrating problem with plasma gasification from my perspective is that it essentially down cycles metals. That is, the metals either end up in slag or as a difficult-to-refine mixture. That was my understanding the last time I wo

Yes! This is one of the ideas I’ve spent time on and am still somewhat curious about. InEnTec is the leading company in the space (as far as I can tell) because they have good scientific leadership, a good academic pedigree, and an investme

I’ve tried to work on this problem, and it is MUCH more difficult than people realize. If you are started with a single product (say a lithium ion battery), then you might stand a chance of developing a process that can recover a reasonable

Thanks for the info. I reviewed it. To me, it seems the problem nobody is addressing is how to recycle valuable metals without them becoming part of the slag (ie we need something that can be used to break down electronic components to thei

While the article mentions stainless, it doesn’t really give it enough credit. Lots of words describing the failures of the Statue of Liberty, but no words describing how the Gateway Arch in St. Louis and the top of the Chrysler building (b

You basically correctly identified the main reasons plasma gasification has not been viable and why it won’t be viable until these issues are resolved. My inquiry basically amounts to whether anyone is working on these problems. There was a

This is what I referenced in my post as plasma gasification. It has been tried in the real world. Belgium planned to use it for landfill mining, and Britain planned to built two plants to process fresh trash. But this has all been shut dow

Sounds like we’re on the same page. As I’ve thought about this, I can’t escape the disorienting feeling that many more filters are in the past than in the future (and ones with worse probabilities are in the past too). Do you perceive the s

What do you propose are the biggest filters ahead? And what do you think are the biggest ones in the past that we overcame?

Would you be willing to list what categories of data are in that file?

One point of clarification: one bit on a classic PMR drive contains hundreds of magnetic grains. It is the grains that flip, not the bit. It would take many grain flips to affect the bit. Errors of this sort do not manifest as flipped bits

Have you truly observed this type of degradation? I do archive work and have 20+ discs from the 2010 era. Mostly the first generation of PMR drives. I have never had any data degradation problems. You can also find lots of YouTube videos of

Where do you get the idea that HDDs only retain data for 5 years? The physics I learned in college suggests they will retain magnetic domains for hundreds or even thousands of years. Yes they can fail mechanically (is this what you mean?) b

Can you explain why YouTube ads seem so scammy and low quality? Or why I can watch two hours of Peacock and see the same car insurance commercial 10 times for the company I already use for my car insurance? These are two examples of an unhe

I mean the site hasn’t collapsed like everyone thought it would 2 months ago. But besides that, I would be astounded if they have actually lost 50%+ of revenue. Keep in mind that few people would actually know those financials, and they wou
