I’ve worked at Bloomberg. The Terminal system is a “very resilient catastrophe machine” that you’d think was vibe-coded. 11 figure annual revenue.

I strongly believe there are entire companies right now under heavy AI psychosis and its impossible to have rational conversations about it with them. I can't name any specific people because they include personal friends I deeply respect, but I worry about how this plays out. I lived through the great MTBF vs MTTR (mean-time-between-failure vs. mean-time-to-recovery) reckoning of infrastructure during the transition to cloud and cloud automation. All those arguments are rearing their ugly heads again but now its... the whole software development industry (maybe the whole world, really). It's frightening, because the psychosis folks operate under an almost absolute "MTTR is all you need" mentality: "its fine to ship bugs because the agents will fix them so quickly and at a scale humans can't do!" We learned in infrastructure that MTTR is great but you can't yeet resilient systems entirely. The main issue is I don't even know how to bring this up to people I know personally, because bringing this topic up leads to immediately dismissals like "no no, it has full test coverage" or "bug reports are going down" or something, which just don't paint the whole picture. We already learned this lesson once in infrastructure: you can automate yourself into a very resilient catastrophe machine. Systems can appear healthy by local metrics while globally becoming incomprehensible. Bug reports can go down while latent risk explodes. Test coverage can rise while semantic understanding falls. Changes happens so fast that nobody notices the underlying architecture decaying. I worry.

@nachkari so the argument is that rate of growth is tied to optimism which is tied to fertility you have some outliers then like Poland where fertility still amongst the lowest in europe i’m generally very Thielian but in this case and imho there are so many clear cultural factors

@nachkari In this instance it’s possible that low fertility is what’s downstream of economic growth. LATAM relatively wealthier, people are relatively more connected, yet fertility tanking for decades.

@nachkari interesting. i suspect fertility rate decline is more cultural than economic, but i was wrong once before in the 2000’s and am humble enough to know it could happen again

@Chris_arnade yeah even one weird thought is that i can’t tell if the replies in this thread are weird or so predictably weird-ish that they’re not weird at all. but this is algo-land

@libovness Can feel monoculture if you only focus on built environment, and/or let the algorithm rule you! Monoculture in the tweets, Multiplicity in the streets

Never really understood monoculture thing. Our built world might look more similar than it used to (every city now at least one brew-pubs that is a defined type), but the people in them are more culturally diverse than ever, more into their niche interest -- sports, gaming, collecting tiny remote control work vehicles (like guy in the bar last night who was part of a worldview micro RC club), My childhood was far more monoculture. Everyone my age watched the same movies, the same TV shows (Roots, Laverne and shirley, etc), saw the same news, listened to same music. Now there's no cultural product I can assume anyone has seen.

Odd thought: There’s never been less of a monoculture and yet everything feels far more homogenous

AI is similar to crypto in that it requires cheerleading, albeit for very different reasons. AI requires cheerleading because it's so obviously powerful it might take your job and fill your life with slop. Crypto required cheerleading because it was so current-world impotent.
