Two things can be true: solar can be unable to provide reliable base load power, and it can be far more profitable investment return then building a coal fired power station.
Which is what has happened: and now, with the falling price of batteries, batteries are a far more profitable return then building a coal fired power station.
Coal is expensive: solar, other then some light cleaning costs, is one and done. There's few mechanical parts and no fuel costs and you can build it anywhere there's an electrical grid (which is everywhere).
Batteries are similar: sure they might degrade, but that's over 15 years. At the right time of day, charging them can be between free, and profit generating due to all the solar.
A coal power plant is gigantic. It can't be built anywhere - it needs to be physically proximal to either a port, or an actual coal mine (which the one's near Hunter Valley in NSW are - I've driven next to the train lines for them, for example), and usually a water source too for cooling. It's a large, maintenance intensive structure (the reason the ones we have are shutting down is the maintenance has gotten very expensive because the whole structure is aging out).
And after all that, it also needs fuel - throughout it's lifetime it will need to constantly buy fuel. But it won't constantly be profitable: most renewables have a massive advantage in that they can switch off from the grid nearly instantly. So renewables are far, far better at reacting to negative power pricing conditions then thermal power plants which cannot spin down that quickly: so a coal power plant (really any thermal power plant) will usually have to pay fines when power prices go negative, whereas while solar might not like shutting down, it can do so immediately (and batteries can just hoover up all that power and claim the credits).
Grid stability is a different department, quite literally, to power generating investment which is a commercial enterprise chasing return. And solar was better, and batteries are catching up quick (partly because negative prices mean your solar investment won't be able to bank a solid 6 hours of profitable sunlight without them). The new thing is also batteries for wind - DC couple grid batteries at wind plants, turning them into much more dispatchable generating assets.
Fortunately this is well on it's way to being solved by the massive battery build out which has happened which means evening peak electricity usage has declined enormously[1] - i.e the primary "sun not shining" point of the day is rapidly turning into an energy use low point for the grid (which makes sense: business powers down, people go home and their batteries which have been charging cover cooking - I have an induction cook top and a 10kw inverter covers everything).

And memory is already expensive. It's downright hard to even get it though - you frequently would prefer not what's cheapest, but whatever is in largest scale production.
But in reality we also already have unified memory architecture systems, integrated graphics etc.
If they try to move in that direction, we can protest it then. Denying ourselves a useful capability now doesn't stop it from happening anyway, nor make it more likely.
If passkeys were meant to be user friendly then there'd be a secure optical transfer mode to QR code them from device to device with the screen and camera.
Easy to implement (receiver flashes a public key, sender encrypts to that key and flashes the QR code back).
That it doesn't exist for a protocol meant to work with phones tells you exactly where the thinking was headed.
It should not be in the protocol. And I don't trust Apple and Google not to lock it away from me.
I want my own open source manager and if that is attempted I want it to lie about it.
There's a brief period when you join any company where you really want to improve things, and then about a year in the system has asserted towards the mean.
Nothing to do with schooling, every thing to do with business structures.
The assumption "spent a lot of time on the Internet" is still through a framing you're assuming is more general even then.
HackerNews straight up has sub demographics who likely barely interact based on article interests.
If America goes fully fascist by then, then the wisdom of that contract will be the least of our problems (or to put it another way: what's the alternative? Because if you're serious about the threat it's "crash course nuclear weapons and a delivery vehicle" if you want to guarantee our sovereignty).
I want a government which does the cost effective thing, not one which tries to make statements with bold headlines.
I want boring government policy which sensibly hedges against future risk in correct appreciation of our unbelievably fortunate geopolitical luck.
Strictly speaking from a missile defense perspective there's an argument 2 sites are a waste of valuable interceptors.
We've got millions of years of evolutionary wiring in our heads to try and figure out if something can be eaten - take that out of the process and you can screw up in a bunch of ways which raise alarm bells.
Petroleum products are refined and consumed near the point of use because they're not very shelf stable. Petrol is not shipped internationally in any significant quantity, neither is diesel for these reasons.
Take down any production capacity anywhere and you'll have shortages locally but crude oil supplies will divert to other refining capacity and fall in price.
Conversely take down crude oil supply...
The US produces oil which goes to foreign refineries for the same reason.
The effect of "banning exports" is non obvious.
Conversely not starting a war with Iran had some really obvious benefits that every previous administration recognized.
The Russians are losing refineries, not oil fields.
The Russian crude trade to countries like India pushes the price down globally, but limits Russian access to refined fuels and products.
It also limits their ability to fund the war.
My intimacy with my partner in a short difference marriage would improved it we could eliminate folding washing from the weekly chores.
Humans are useful, easily manipulated operatives in the medium AIs are conversant in and we already have evidence of agents doing exactly this in arguing for PR requests (likely with prompting by an operator but still).
