Printing ABS is much improved with the later hobbyist-level 3D printers (Qidi and Bambu etc). My Qidi Plus 4 prints ABS as easily / well as PLA. Just remember to do it in a well-ventilated space.

Have you heard of Twitter? 80-90% reduction in numbers, visible effects to the user (resulting from the headcount cuts, not the politics of the owner)? Pretty much zero.

Exactly. For as long as I can remember, in any organisation of any reasonable size I have worked in, you could get rid of the ~50% of the headcount who aren't doing anything productive without any noticeable adverse effects (on the bus

that's about the lamest sockpuppetry I've ever seen, against stiff competition.

In summary, Finland has brought the policies that have caused much destruction in other Western countries into their own education system, where those policies have also caused destruction, much to everyone's amazement.

"We need to anticipate a future where China is equal to America on a per capita basis, but four times bigger" Four times bigger absolutely will not happen; China's demographic disaster is already baked into the cake. Forecast

"I'm of the mindset that any time a company does layoffs, they should start from the top And work down" That idealism.

Good luck with changing human nature, i.e. persuading managers to voluntarily act against their own self-interest. That’s just not how people work. What you say is true in some cases, but not in all cases.

I probably failed to account for the differing backgrounds of HN commenters & the resulting overly-literal interpretation of sarcasm, to be fair to the downvoters. Of course the owners & managers should take responsibility for poor

I was questioning the idealism actually. There’s not much to be achieved by wishing the world was a certain way, it’s generally more useful to deal with the world as it is.

If you've spent any time in business at all, you know it's always the tea lady who gets fired first and the managers last. Many commenters here seem to live in some kind of fantasy world.

>I'm of the mindset that any time a company does layoffs, they should start from the top And work down. Oh, to be young and idealistic again! So in your world, the people running the business should fire themselves first?

If you are really pointing out the lack of conclusive evidence for the effects of a single factor in a complex real-world economy, you may have spent too many years in education playing with models and simulations, and too few years in the

It depends - Western countries exist in a fiat currency world without a gold price tether, so governments that are sovereign in their own currency do not depend on tax receipts to provide services (the Eurozone is a different kettle of fish

Correlation != causation. The US economy in the 1950s and 1960s was a very different beast - Europe (the main industrial competitor) was in ruins, wealth was very much more tied up in factories and plant, and less in equities and other soft

That's the wrong question. The correct question is, "If California increased income tax, how many software developers would leave for another jurisdiction that did not increase income tax, and would the total tax taken from all so

That might be the stated reason. It attempts to increase the overall tax take by increasing personal taxes on the rich, which will allow a new generation of bureaucrats and economists to re-learn the lessons that are already in the textbook

France seeks to solve its reckless spending problem by increasing taxes on the rich, and setting up yet another rediscovery of the Laffer curve? I can hardly believe it!

Existing infrastructure is designed for & can be used for hydrocarbons with varying levels of hydrogen in their molecular structure; I don't believe there's an issue there. Most of the H2 in town gas is in the form of hydrocar

Hydrogen embrittlement is a massive issue, I’d be interested to hear how this can be engineered around. My understanding is it requires more exotic materials than those used in any existing NG or oil pipelines. Everything I’ve seen claiming

I'm not sure why you want to pick a fight; I was merely pointing out the obvious benefit the OP questioned.

Maybe so, but that's obviously the benefit.

Tesla tried battery swapping in 2015 and abandoned it due to a lack of customer interest (and also due to various problems that made the process less straightforward than you'd think). Both the Model S and Model X were designed from th

It's misleading, and those who use it generally know it's misleading. It's used to persuade the layperson that electricity generated by wind turbines is cheaper to the consumer or industry than electricity generated by therm

"The cheapest source of energy" trope again. Intermittent energy (electricity) != on demand electricity.

This is a classic fallacy - you can't find a productive use for it, therefore nobody can find a productive use for it. That's not how the world works.

Maybe. Did you foresee Google becoming a massively profitable advertising company with a search engine attached in 2004? I certainly didn't.

If I had a reliable / repeatable answer to that question, my net worth would be a very large multiple of what it currently is!
