one purpose: make bitcoin everyday money
bitcoin has achieved over a decade of 99.99%+ uptime - no reboots, no centralized failovers, no downtime since 2013.
a globally distributed system reaching deterministic consensus every ~10 minutes, secured by thermodynamic proof and open-source minimalism.
this is software engineering at its finest.
when the dark closes in, keep pushing. the smallest spark can light the way #grit
incentives > mechanisms > process > good intentions
during elections ask yourself, is the candidate pro-decentralized, pro-freedom, pro-empowerment of people?#canadaelections2025 #cbdc #bitcoin
open source is freedom. no gatekeepers, just builders.
seeing lots of questions around #bitkey and #opensource. cheers!

square. backend. systems. i know them well. as a fullstack engineer, i've always built world-class backends while struggling with ui. always felt incomplete.
ai changed everything. now i build complete products world-class in every area, on my own. backend and frontend. systems and experiences. built an e-commerce platform in a weekend. integrated with square. fast. beautiful. 10x less cost than woocommerce.
this is what ai enables: complete creation. from concept to customers in days not months. the addiction is real.
the feeling of building end-to-end world-class products alone is powerful. hard to stop when you can finally make the complete vision real in days.

what if wearables and health tracking are like quantum observers of our bodies - changing what they measure, creating anxiety feedback loops, crowd-sourced norms and hive-mind health? are we still in control of our well-being - or is the data?
in quantum mechanics, observing a system collapses its wave function - it picks a reality. what if measuring our bodies does the same? every time you check your heart rate, glucose or blood oxygen, you might be forcing your body into a fixed state.
your body isn't a static dashboard - it's a dynamic process. but constant tracking turns it into a slideshow of health "snapshots". is your body still free to self-regulate or is it always being pinned down by the observer: you?
over time, this can create a rigid sense of what’s “normal”. feeling good might matter less than looking good to the monitor. you become a manager of metrics, not a participant in your own well-being.
now add anxiety. you see a small uptick in your heart rate. you worry. that worry raises your heart rate more. your device flags it. now you're spiraling. health becomes a feedback loop - and the tech meant to reassure you does the opposite.
what happens when the norms aren’t even yours anymore? imagine billions uploading vitals into a real-time global average. your health gets judged against a crowd-sourced “normal”. medical standards become fluid. you’re only as healthy as the "system" says you are.
take it further: a spike in stress in one city triggers ripple effects globally.
wearables sync. vital signs echo across populations. is your fatigue yours, or did you catch it from others? health becomes a hive mind phenomenon.
prediction makes it worse. your device says: “70% chance of a migraine today”. you stress about it. you get the migraine. like the observer effect in quantum physics, the act of predicting may cause the outcome.
now imagine quantum-level monitoring. tracking cellular changes before symptoms appear. you stop disease before it starts - pure prevention.
but maybe we over-correct. life becomes a game of constant tweaking. always fixing, never just being.
so what’s the endgame? health as a lived, intuitive experience... replaced by metrics, algorithms and collective data. the act of watching ourselves is changing what we are.
final thought: if observation shapes reality, then constant self-monitoring might be reshaping health itself. are we still deciding what “healthy” means? or is it the act of watching that decides for us?
if you ain’t learning fast and growing every day, you’re already falling behind
figuring out who you are is tough. in the end, we’re all “one-of-a-kind” llms - different context windows, token caps and bias dials
compare different model responses to get a more critical view. interesting https://plado.ca
take ownership. nothing’s someone else’s. no excuses. own it fast. build it now. never ‘not my job’
