At the Inaugural Unconference Patch alumni could host their own sessions and promote open-source, peer-to-peer learning. Had some really great conversations with future planning in mind... Shoutout @aidmcn for organising and @TimFarrelly8 and @LucyDaly19 ⭐️⭐️⭐️⭐️⭐️

This is one of the most astonishing pieces I’ve read in recent memory, proposing a new theory for why the universe is structured the way it is It essentially applies evolutionary biology to the creation, destruction, and development of universes, as if they are living entities evolving according to natural selection The “blowtorch theory” that emerges from that model seems to explain so many problems with the standard model based on dark matter/energy, and doesn’t require new physics or disregarding common sense I feel like my brain’s conception of the universe was just expanded orders of magnitude in scale, and yet because of the biological parallels, the universe also now somehow feels far warmer and more intimate Even if this theory is wrong, that feels like a tremendously powerful mental model to use. A radically different perspective that reframes many questions including the origin of life, consciousness, and technology It’s also written with incredible wit, personality, originality, and poking good fun at other scientists, without devolving into pandering or crudeness. That would be rare in any piece, much more so in a science one I can’t recommend it enough. Link below

Had a Mag7 co reach out to ask about space data centers and why we're so bearish on them this week Thought I'd need to prepare a talk track but no, I can just use this brilliant work of art:
Andrew McCalip@andrewmccalip

Data centers in orbit? Of course that’s your contention. Of course it is. You just finished watching a Scott Manley video on radiative heat transfer and now you think you’re gonna disrupt AWS with a few solar panels and a rideshare slot. You’re gonna believe that right up until next month when you crack open DeWitt and Incropera and start throwing around σT⁴ like you just invented radiation physics, quoting emissivity tables for polished aluminum like they’re forbidden knowledge. Then you’ll finally open SMAD and realize your radiator isn’t some static plate glowing into the void. It’s a dynamic structure with a wicked case of thermal flutter reminiscent of Hubble’s arrays. You’ll be quoting beta angles and Earth albedo coefficients and wondering why your deployable array grenaded in vibe when the first bending mode clocked in at 38 Hz instead of the 50 Hz you promised in CDR. After that you’ll get real ambitious, quoting Johnson and Fabisinski on inflatable polyimide PV structures, pretending you actually understand what happens when your 25-micron Kapton sail is tensioned off a Toray T1100G Cycom 5250-4 boom that has been sun-baked at 120 °C for six months in LEO. You’ll cite “areal density optimization” like gospel while your resin creeps, your modulus drops, and your perfectly flat film turns into a potato chip. "Well, as a matter of fact, I won’t, because launch costs are about to fall another order of magnitude once Starship hits cadence. The cost per kilo will—" Drop by tenfold and the economics flip. Yeah, I’ve heard that one. The Wired 2012 quote, “You wouldn’t build a Boeing 747 and throw it away after one flight.” I remember. I even asked him about that over lunch once, whether the market was actually elastic enough to handle the supply increase from reusability. Turns out it wasn’t. Non-Starlink launch mass in the United States grew at 13.7 percent CAGR from 2015 to 2023. Payload demand didn’t scale with flight cadence, so prices didn’t collapse, margins just swelled. That’s why they had to invent Starlink. When the market can’t absorb your rockets, you start building your own payloads. Is that your thing? You read some Marc Andreessen “American Dynamism” manifesto and suddenly start ignoring the engineering realities? You start throwing around a few buzzwords to impress the Twitter anons and earn some street cred for having a contrarian opinion? One, don’t do that. Two, you dropped a 500-thousand-dollar seed check on a concept that could have been debunked by a dollar-fifty worth of tokens from Grok. "Well, at least I’m a capital allocator. We’ll be skiing in Hokkaido while you’re doing bolt preload calculations for some bridge somewhere." Yeah, maybe. But at least I won’t be unoriginal or anonymous. I’m out here asking why the hell we’d melt the brains of a thousand aerospace engineers just to save four cents per kilowatt-hour on solar electricity. First principles isn’t about getting nerd-sniped by a shiny-object problem. It’s about asking whether we should be solving that problem at all. But hey, if you’ve got an issue with that, we can always take it up with E.

They will run 24/7, 365 and pay whatever it takes to force everyone else off the grid so they can keep doing it

This is only revealing itself during the peak parts of the day, since there's enough supply to go around at night. It will raise avergae prices which will only get passed on to consumers.

I had a little poke around today in the US energy data, looking specifically at the effect of all the new AI datacentres. What I've done with this chart is isolated the LMP (locational marginal price) for the hub closet to Ashburn, VA - "Data Centre Alley" 1/n.

i keep thinking about this our cells have no awareness that they're part of a larger consciousness does this apply to us as well there's a larger consciousness that we're a part of but we as its individual cells only perceive ourselves and our immediate surroundings

@casholeary What should be done is 2 classes of cap gains tax. 33% for investments outside of Ireland, and 10-15% for anything (non real estate) within- get the wheel turning

I hold an opinion that enterprise Ireland should be scrapped and so should most govt related funding for startups. It should be replaced with tax breaks & incentives for founders. Govt distorts mkt by propping up co’s that wouldn’t attract private investment anyway.
