Respectfully, I believe you have confused "new" with "state of the art". China is likely using batteries because their battery production is subsidized, Australia's trading partner is China so basically equivalent.
Perhaps a bad analogy, but it seems these battery systems attempt to stabilize by "pushing", whereas spinning mass can also work through "dragging" the phase. So eventually, you will have just a few rotating masses setting the freq and phase, with more and more systems tracking that and pushing, which seems like a recipe for chaotic equilibrium.
No, they are doing that because they have a ten year head start on the rest of the world. The US & EU not having done their homework is entirely on them. The US is choosing to pump a lot of funding into fossil fuels instead. You could say that China is simply spending smarter.
The rest is just economics. We might suck at making batteries. But we suck even more at making new gas/coal plants or fueling those cost effectively.
Anyway, this stuff is being deployed by the hundreds of gwh per year now. Much of it in China but some non trivial amounts in places like Texas and California as well. As a result, the grid is actually getting more stable, not less stable.

This is comically wrong. You're just making things up. Australia is at the forefront of this new tech due to necessity and some good luck. Scroll to the bottom of this article and have a look at the graph. It shows Australia has 5 times the grid forming battery infrastructure deployed or under construction than China or the US, or pretty much any other country. It is very much SOTA, needed for a grid that is a rapidly changing mix of rooftop solar, hydro, coal, gas and wind spread over a country the size of the continental US. Rotating masses are not going to cut it.
I have something similar from AT&T about my fiber internet, they kept sending me "transactional emails" with the last 3/4 of the message body being marketing copy for their phone service etc. I submitted a complaint at the FCC (consumercomplaints.fcc.gov) and got a very fast followup from the "Office of the President of AT&T" putting me on an internal do-not-solicit list and the emails have generally gone away. They even had to write a case resolution letter to the FCC. This "loophole" in the CAN-SPAM seems to be spreading across different industries not just the NYT.
I'd be curious to see a breakdown between the "toxic chemicals" and "suffocation hazards" categories, as my intuition says it's mostly the latter and often bunk. The other day I was watching the TV above the Walmart customer service desk that displays product recalls, and multiple recalled products were a motorized bassinet, but the wireless remote control has a battery compartment that could be opened and then the battery swallowed. To a layman or (I assume) Chinese inventor, that seems overly burdensome as I am certain that same household would have other wireless remotes.
> "suffocation hazards" categories, as my intuition says it's mostly the latter and often bunk.
Are you US-american? (Walmart is a good hint that you are.) There's some widespread misconceptions/prejudice there, e.g. the Kinder egg thing. The EU has no problem with selling those.
Yes, I know this is an EU article, but I suppose we have similar Temu garbage here in the USA to deal with. I wish for more reasonable restrictions but more severe enforcement, as these "bad" product examples I mentioned seem to make people lose interest as they seem silly.
It's well within the realm of possibility that a parent, holding the remote, approaches the bassinet and sets the remote down in a location where it's reachable by the child. Perhaps even in the bassinet! And especially so if the wireless remote is the only way to operate the bassinet: are you going to walk across the room to turn it on?
Not to mention, new parents are often some of the most sleep deprived. The burden should be on the manufacturer to make these safe. And it's not even that hard: just use one of the clasps on the battery compartment that requires a coin or key to open rather than just your fingernails.
People forget many of US's regulations were written in blood because the US already had it's industrialization period. They left behind signposts that people could use to sue.
The US seems burdensome because some US Entrepreneur already tried not caring and something happened. A good comparison is China cars which don't pass US standards for import. It's also a reason US Makes can't iterate as quickly as they aren't allowed to do the same things that China Makes can to iterate fast.
Whether or not it needs to stay that way is really the only question. I think most reasonably intelligent people read things like suffocation warnings and go, "well obviously don't do that." But the regs are written for the people who aren't that bright who will do it anyway.
I think Polyolefin Primer (Permabond POP) is magical in what it can superglue. Beautiful chemistry allowing something like Teflon or steel to be glued. https://www.youtube.com/watch?v=G9yz8OqThJk
Regarding hardware, it's not entirely true that it doesn't need maintenance/development. See "stepping" https://en.wikipedia.org/wiki/Stepping_level. There are sometimes ways to tweak the masks to fix a "silicon bug".
Yes, but that still costs significant money in a way that software deployment doesn't. IME most chips get maybe one or two metal layer revisions then a rev B consolidated bugfix - and then get left alone.
Yeah, my experience has been exactly that. And the person paying the bills will try as hard as possible to avoid/delay a metal rev as possible because they’re expensive and time consuming so they blow up the schedule if you can’t release the chip with rev. A.
One place I worked at did fast iteration by pushing as much of the risk as they could off the silicon and by using several distinct ASICs instead of a single monolithic one which would have had better performance on its own. Gave them the ability to rev the different parts at the rate they needed it at a cost to software complexity and hardware compatibility and cost.
I caution PayPal would only work if you trusted the original shopping site, and perhaps your "credentials" got breached and used illicitly elsewhere. I got banned from PayPal after I tried to buy an electrical switch, was on an (apparently scam) website, never received the item, and opened a PayPal dispute. The scammer somehow convinced PayPal the item I tried to buy was illegal/against PayPal ToS, which resulted in them banning *me* instead of the scammer.
On the other hand, I see an unknown charge on my credit-card, dispute with my bank, and it's handled.
There's somewhere in the ballpark of 166,000 employees at Apple, just unfathomable scale [1]. It is not unreasonable to ask that someone specific is responsible for each particular small feature and ensuring it keeps working. Trying to apply an economic analysis to such a "free as in beer" operating system does not seem to work well. Consider the question of "how many small holes can you have in your wooden sailing ship"?
