(like I said..) I'm impressed with the prowess of the MATERIALS SCIENCE in companies like 3M and DuPont, certainly not the business ethics. Please don't conflate admiration for the fascinating engineering work with endorsement of an entire company's impact on the world!

3M certainly do good some science, they just had(?) a terrible engineering ethics problem.

> Fluorinert is a super niche product. I mean, that goes both ways. At that price it will always be a super niche product, and never graduate to "plain niche". Look at the enthusiast market, there's no lack of fancy water cooling gizmos out there. They're bought by a small segment, but there's still a market for fancy gizmos to provide the best cooling for overclocked high end hardware. And that's exactly what I'm ge…

I suspect some of these products have a funny price curve. If Fluorinert costs $300/litre today and you cut the price to $100/litre - that's still far too expensive to become a mainstream PC coolant. It's not like there's a proven market for mineral oil PC cooling. Could be, if you cut the price of Fluorinert by 2/3rds, you'd just be giving a discount to your existing customers, for whom price is no object anyway.

Mineral oil is _very_ messy, which really doesn't help at all. And the one company that sold the tanks had to stop due to some patent nonsense.

A while back I invested in 3M because it's a company that makes so many amazing and industry leading products and I thought they'd do well. A couple years later and the stock is just lagging. I guess they're dragged down by their environmental lawsuits these days. As a human, I'm appalled at their environmental track record but as an engineer, wow they really do so many things so well.

At least part of the reason 3M stock price doesn't rise as much is because they distribute a dividend.

Not sure if you'll consider this a more scientific source, but John Oliver also did a piece about PFAS: https://m.youtube.com/watch?v=9W74aeuqsiU . The list of issues that the wiki article claims are "high certainty" is also quite concerning to me: https://en.m.wikipedia.org/wiki/Per-_and_polyfluoroalkyl_sub... At the very least, seems that the production is being ramped down - quick skim of the article yielded this…

John Oliver is a comedian, so also not a very good source. It's written for entertainment rather than being informative.

That's not true, John Olivers show is extremely well researched. Sometimes his lack of references make it hard to use him as a source, but you can use the show as a starting point and validate his claims from there. They hold up very well.

What about that did you not understand? You have a corrupt government, where no law gets passed without input from corporations via their lobbyists. They have this access because they pay bribes for the privilege. That's banana republic levels of corruption. The reason this is relevant is because your FDA and EPA are both captured organisations, which is what allows Dupont and these other environmental terrorists to…

The US government is very far from "the most corrupt" legislature in the world. I agree it's quite corrupt, though.

When you use corruption in the sense of committing corrupt illegal acts, the US looks fairly clean. But if you define it in the general sense and include lobbying and sacrificing the public interest for private interests as corrupt, then in terms of the dollar values, US legislative systems are some of the most corrupt anywhere.

That Netflix link is not available everywhere and also quite time-consuming to review. Obviously it is also a dramatic piece rather than a (semi-)scientific. I had a brief look at the PFAS wikipedia page ( https://en.wikipedia.org/wiki/Per-_and_polyfluoroalkyl_subst... ), which is what that Netflix movie seems to be about, but it's also quite wordy and the claims you make can not be found on there as-is. Maybe you wa…

The intercept brought a lot of this to light: https://theintercept.com/search/?s=pfas

The issue is that when you remove social and environmental ethical constraints, a lot of companies would become impressive in a technological, financial or managerial sense. But if you include them and measure 3M's, Dupont's etc. performance in a strong regulatory environment with good compliance, they earn decidedly unimpressive overall scores and can be seen as bunch of greedy, clever, selfish parasites, gaming the system.

That's why narrow statements praising one aspect of their performance paints half a picture. Like calling a war criminal an effective tactician - technically correct, but against the big picture, so what?

If you didn't already know, 3M shareholders can sign up for an annual holiday box. It costs money to order, but it's still much cheaper than buying the individual components (although if you don't need command hooks or post-it notes it might not be worth it for you) Full disclosure: I am the proud owner of one share of MMM.

What’s in it and what is the cost?
