Adding a sentence to explain how ARM "saves the planet" would perhaps be more effective than a hash tag. I presume you are referring to lower typical power consumption for ARM servers.
Off topic but I think we are at the point of no return. Plastic pollution is at its highest with production and use of plastic to increase in significant magnitude by 2050. The main generators of green house gases (US, China) have yet to reduce their reliance on fossil fuels. We are constantly over-fishing, over-grazing, deforesting and plunging this earth of its precious resources with reckless abandon to feed our decadence.
World War III won’t be a fight over “values” but rather a constant fight over who controls water, energy, and clean air.
Or at least for the least 20-30 years. Sure theoretically there was long term a way to salvage it. But it was always unrealistic given the large change in economics and society it requires.
But there is a difference between a bad and a even worse situation.
So just because we can't reach a perfect outcome doesn't mean we shouldn't try to reach a better outcome.
Because of this I really don't like arguments like "we are at the point of no return" as it's often used as a argument that supposedly any improvement is pointless. (Through I think you do not mean it that way).
I mean the way we are heading will like not directly lead to a extinction of humans, but it might make live unbearable for most of humanity and it also might prevent us from reaching the necessary tech to survive other extinction events.
But this also means that "just making thinks a bit better" can in the long term have a major difference even if it won't prevent a climate catastrophe.
World War II wasn't much of a fight over "values" either, that was largely a propaganda device. Certain powers simply wanted more stuff than they already had, and other powers disagreed. Britain declared war when Germany took a Polish port, not when Hitler got in power or when he started rounding up Jews.
Britain declared war when hitler took Gdańsk, sure... but after hitler took Czechia and Austria (and funded a coup in Spain). so it’s fair to say Britain’s declaration of war was initially mostly about stopping an expansionist power... but I don’t see how that’s the same as propaganda
Going back _would_ save the planet, but it's not the only way.
There are routes forward, but they require global coordination and creativity. It's hard to imagine because there's no historical precedent, but I think it's worth trying for, and I'm confident it's at least _possible_ we can succeed in transitioning to full sustainability.
