Obviously, who will be their parents, as that directly leads to whether they're urban or rural dwellers, smokers, wood/coal/gas or electrically cooked meals - perhaps with a private chef in the chefs kitchen with their own air filter, how new their cars are and whether they're EVs or not, those types of things.

So if anyone's to blame for poor lung health in children, it's themselves for picking bad parents.

It's a top-down approach - when your federal government is fully entrenched in graft and corruption it tends to increase those at lower levels of government as they can see there's no accountability for their own bad behaviour. Start with your political parties and demand honest, law-abiding, and trustworthy candidates for office at every level.

Nuclear power is banned in my country, so I'll be thousands of km from the nearest generating reactor - even the test medical ones we have are 1000+ km away.

We'll get our renewable power primarily from firmed solar, wind, and hydro sources. Heck, ATM now we're a little over 50% renewable supply for the entire country. It's going to continue increasing.

BYD started making batteries, and when it was successful enough there it branched out towards making cars - and along the way vertically integrating virtually their entire supply chain.

Other car makers are dependent on external suppliers, and this shows in their inability to screw down costs.

I'm working towards what you have - currently have solar installed and a 20kWh battery coming next week (biggest I could install). My solar array has been generating ~16MWh annually since I installed a few years ago, and our overall consumption is about 5% lower than this (in large part because of increased consumption during the day) - though without a battery we're running on-grid overnight. Be interesting to see how much demand the battery can cover. EV charger also getting installed - we haven't bought an EV yet, but will get one to replace one of our ICE vehicles when it's time to do so.

That's legit amazing progress.

I just looked out the window from work (37 floors up, close to the CBD centre), I can see some landmarks at least 60km distant. We only have smog now when there's forest fires.

About the only thing missing are AR glasses, which I understand they're working on. The other hardware I've heard of (cars, TVs etc) seem to have been dropped, which IMO is a good thing. Keep the mobile devices and integrate with other things.

This seems the most sensible solution currently - sure synthetic avgas will be expensive, but retrofitting or replacing every plane in existence, plus all the storage refitting, transport, and generation - surely there's a point at which it makes sense to use the synthetic fuel instead?

Are we primarily waiting for excess renewable energy to reduce costs enough to make it viable?

I believe there was a documentary predicting this exact scenario?
Stupido, Dumb and Dumber, Idiocracy? Something like that.

What we need are the programmers from the 70s, 80s and 90s that went into those cryo-sleep chambers to wake up and rearchitect these codebases from scratch in Assembly and C.

The laws aren't about whether the user is considered an adult or not, but how old they are. That means the website needs to be able to know if the user is XXyrs old or not.

If the OS stores the user account birthday, whatever API is used should ask if the user is XX yrs old or not and the OS gives a TRUE or FALSE response. No other data should be available, and the website should only be able to ask this once per cookie/session where an account is not saved.

What becomes more complicated is a shared device such as a smart TV - does the TV need everyone's account or does it default to child-friendly mode for general operations, and you need to login to a service that has your birthday so as to allow for adult access?

I don't know if you track this, but I am - and some SaaS companies love the annual renewal dance where they throw out eye-watering annual increases (25+%) and then graciously dropping it a bit like they're doing you a favour by only going up by 20%.

It doesn't have to be opensource, it needs to be feature similar and cheaper to attract eyeballs. The example in the summary (holosign) would be 1/50th or so the cost of our current sign solution. That type of savings has CIOs wondering whether they should chance the newcomers and risk nil real support or stick with existing systems that have a known support system.

And that's for a 5-figure system. When you've got 6 and 7 figure costs for a niche toolset, you gotta wonder whether it's worth attempting your own code.

Do you live on a south pacific island? Cause they can tell you that their homelands are disappearing under rising sea waters.

You may not notice but others certainly are. In the past decade there's been more cyclones coming my way than the previous 4.

It really depends on who's judging as to whether your argument might progress. For example, I very much doubt that any sort of criminal proceedings will progress against Donald Trump while the republicans are in power and can appoint their puppets to the DOJ - regardless of how good the evidence (if allowed to come to light) might be.

Meanwhile across the pond we're seeing considerable backlash and consequences to politicians and (now ex) royalty through mere association with Epstein.

IMO the primary difference between a civilised and uncivilised society is how they treat those unable to provide for themselves.

This currently seems to range from:
Throw them to the wolves, to
We'll clothe, feed, and house them, so that they have the opportunity to do the same for themselves and others.
