people forget that data isn't a fungible commodity more data doesn’t automatically mean better models. quality, diversity, and relevance matter, not just volume that’s why i think the race for the right data will be more interesting than the race for compute and power

high-quality data is the bottleneck at the frontier right now anyone telling you otherwise is just coping automation never ends. you automate one function, freeing humans to take on new tasks that eventually become candidates for automation themselves the cycle continues data might just be the fastest-proliferating asset class of the decade

the easiest way to get hired
i'm begging you: - pick 10 startups that raised a seed round in the last 6 months - sign up and use each product like a real customer for one day - write down every spot where you got stuck or confused - pick the 3 worst ones and record a 2 min loom showing how you'd fix them - send it to the founder on X with one line: "used [product] today, here's what i'd fix first"

re Spirit Airlines data: if you train a model on a failed airline's emails you will get a model that is really, really great at running a failed airline

Guys, I don’t review apps! I can only recommend the top ones to the a16z speedrun partners, and those apps will most likely get looked at :)

Would do another 12 weeks just to work with Josh again
Despite having experienced every cohort so far, it always surprises me just how much a driven, ambitious team can get done in 12 weeks. I've seen companies go from a standing start to putting a real dent in the world. I've seen teams multiply in size, gobbling S tier people along the way and turning their company into a gravity well for talent. I've seen revenue/usage/DAU go parabolic SR008 applications are officially open. Show us what you'll be able to do in 12 weeks. It's time to apply (link below)

how can meta ads be this bad? it’s like none of the filters i set are respected 25+? i’m getting 16 year olds. within the us? i’m getting people all over the world and no, i didn’t use advantage+ if that’s what you’re wondering i understand it self-optimizes, but it’s supposed to self-optimize within the boundaries i set can’t believe one of the top 5 companies in the world has its largest money machine this broken

vibe working is going to have the exact same consequences as the early days of social media you can deny it, but I’ve been talking to hundreds of agents every day, with entire swarms basically running departments in my company like they’re fucking employees I expect them to respond instantly. I expect the work to be perfect. If it isn’t, I just threaten them and tell them to try again. There’s no waiting, no capacity, no stopping cue it’s the same easy dopamine loop social media created, except instead of infinite social validation, it’s infinite agency: thought → command → work happens → result over and over again there’s no way this doesn’t do something to our brains
