    Well green hydrogen is also a necessity if you want to make carbon-neutral synthetic hydrocarbon fuels.

    Dr. Asperger may or may not have been sorting autistic children into high- and low-functioning groups so that the higher group (with “Asperger’s”) could go on to become good Nazis …

    YMMV, I guess - we were surprised when our first grader said math was her favorite part of school this year, and she recently asked if she can get i-Ready on her iPad.

    Haggling with DoD over contract terms and losing out is utterly routine. Ending up labeled a supply chain risk as a result is not.

    Honestly, this makes me almost feel better about the whole situation. I had been finding it super unsettling: Like, why would DoD go nuclear over wanting to build fully autonomous …

    As much as it pains me to say it, this is a plausible answer in 2026

    Lack of pull-through charging stations is a very big hurdle too.

    It's insane to me that this even needs to be written – showing you care is just not that hard! And it absolutely doesn't have to come at the expense of business goals. I've had som…

    I think it helps to remember that those posts are basically sales pitches, and that if they don’t resonate for you, then you are probably not their target audience. But another thi…

    Sure, but even assuming OpenAI gets to a tamer 20% net margin, 25x earnings wouldn’t be surprising so they’re raising on a projected $60B/yr revenue which might not be where they e…

    Just picking a semi-related stock, NVDA trades at ~30x gross revenue, so a $300B "only" translates into ~$10B in revenue. And OpenAI can ask for a better multiplier because I'm sur…

    I mean if we’re doing analogies here, I’d say it’s more like you said “the sky’s always blue in the US”, and I said “actually it’s kind of cloudy here right now, and in fact it’s o…

    Oh for sure it’s skewed, and it doesn’t surprise me that there are people that will get 20+ CTs. Wild that that’s the average though - the skew must be massive.

    Comment #44629867

    Well apparently there are ~40m MRIs per year in the US, implying around 9-10 lifetime MRIs, which seems... pretty high? It's also wild that, at 85-90m CTs per year, apparently the …

    Comment #44629192

    Okay that’s a very surprising number of MRIs… I’m in my early 40s and have had 1. Everyone I know well has had 1 or (more typically) none, including my parents and in-laws, so I fi…

    Agreed. MRI machines are not the bottleneck - we have 3 in my area, serving maybe 100k people. Assuming most people are like me and spend about an hour in an MRI machine every 40 y…

    Right. I still don’t think your original contention that for-profit systems are, in general, orders of magnitude better than socialized ones is accurate, but I do concede that your…

    Six weeks is also very far from “immediate” EDIT: Spot checking in a Canadian town with similar demographics as my own shows wait times roughly comparable to mine, and nothing anyw…

    I’m lucky to schedule an appointment of any kind less than 8 weeks out, unless there’s a cancellation. Recently, it took me like six weeks to get an MRI to diagnose a broken pelvis…
