<p>I think the nature of war has changed. A slow moving swarm of drones, will keep large Aircraft carriers well outside the range of their fighter jets.<p>A nation can swarm an aircraft carrier with a 1000 drones, each costing about 40k USD. Only a few are needed to seriously damage the carrier. Not to mention ballistic missiles.<p>In this scenario, does a US massive, slow moving aircraft carrier possibly carrying hundreds of billions of assets really work ? Can the US meaningfully project power with these?<p>In this scenario, who holds more power or leverage ?<p>An aircraft carrier can project power within 500 miles. The idea is to use a few of these to knock out the air power of the opposing nation, basically airfields, missile stockpiles, factories, power infra, etc. And then drop in a ground invasion force.<p>Does this now work? I dont think so. 10 drones can be launched from the back of a truck.</p>

<p>Because all the variables that go into performance / efficiency measurement of a model (processing power, algorithm efficiency, parallelization, etc) boil down to cost per token input and token output. And the tangible cost for a datacenter is power consumed. Of course, amortized capex costs are also part of the game.</p>

<p>This is the inflection point for the beginning of culling of the intellectual class. If not physically, atleast economically and socially.<p>A few arrests and a few in detention centres, will be enough to make them fold and grovel.<p>They are now categorised as "radical left" and woke.<p>The elections will be controlled to "prevent the radical left take over of the greatest country on the planet".<p>edit : The stage is also being set for total media control. My prediction is that the next target will be Google, specifically Youtube. You should start seeing talks about how the radical left is inflitrated youtube.</p>

<p>On a side track, I wish to express my fears regarding AI<p>Unfortunately for the general populace, most technological improvements in information technology, for the past 5 decades, has lead to loss of political control and lessened their leverage for political change.<p>With AI, this change is going to be accelerated a 100 times.<p>With current AI slop, and more importantly, almost indistinguishable from reality, AI based content, the populace is going slowly learning to reject what they see and what they hear from mass media.<p>AI has muddied the pool so much, that every fish, us, cannot see the whole pool. What this will lead to, is for political figures and bad actors to, much more easily almost with no effort at all, create isolation among people.<p>No event will create a mass uprising, because no event can be believed by a common mass. It will be easy to generate an alternative reality using the same AI.<p>Now, the political class and the billionaire class, are free to act with impunity, because the last check on their power, the power of mass media to form public opinion, to inspire the masses to demand change or accountability, has eroded to the point of no return. (They have already captured the institutions of public power)<p>I fear for the future of humanity.<p>Edit : There are already troubling signs from the billionaire class regarding this. There is a narrative to "ensure guardrails" for AI, sort of giving the populace the idea that once that is done, AI is acceptable. This is like saying, "better have a sleeve on the knife, so that no one can cut with it, but use it as a prop in a movie"<p>They are creating this narrative that AI is inevitable.<p>They are fear mongering that AI is going to take jobs, which it will, but it also goads the capable ones to get on to the bandwagon and advance AI further.</p>

<p>Good luck trying to take something back from the populace once already given for decades, even if it is in a limited form.<p>It's a desperate attempt, that really shows how cornered the administration is.<p>Any power that fears information, has to have a highly fine grained, high level control of information to maintain power. This is absolutely difficult, in a country as culturally diverse and with a long history as Iran.</p>

<p><a href="https://iopscience.iop.org/article/10.1149/1945-7111/abae37/pdf" rel="nofollow">https://iopscience.iop.org/article/10.1149/1945-7111/abae37/...</a><p>This is the paper that claims 10,000 cycles under optimal conditions.<p>But if you read it, they measure Equivalent Full Cycles, and it seems that implies 10000 cycles at partial discharge, not full discharge.<p>The paper calculates everything at nominal discharge upto 80%. Meaning, the installed capacity has to be 25% more than paper value, leading to increased costs.<p>Add to that, batteries are complex to manufacture, degrade, lose capacity, etc. You need high level of quality control to actually ensure you are getting good batteries. This means, the cost of QA and expertise increases. They are costly to replace, even at an avg of 3000 cycles (roughly 10 years). Bad cells in one batch accelerate degradation and are difficult to trace out. Batteries operate best at low temperatures, so the numbers may vary based on installed location and climatic conditions.<p>A turbine and co2 compressor system is dead simple to manufacture, control and maintain. A simple PLC system and some automation can make them run quite well. Manufacturing complexity is low, as there are tried and tested tech. Basically piping, valves, turbines and generators. These things can be reliably run for 30 to 40 years. Meaning, the economics and cost efficiency is wildly different.<p>With such simplicity, they can be deployed across the world, especially in places like Africa, middle east, etc.<p>On the whole, batteries are not explicitly superior as such. There are pros and cons on both sides.</p>
