Before AI, I’d spend a weekend building 1 useless app.

Now I can build 67 useless apps over a weekend, each with a logo, a fancy webpage, and 0 user.

Positive users praise AI's productivity gains that let a developer rapidly build dozens of apps, while negative users dismiss the output as useless noise without quality or real users.

Weird. I made a webpage with AI that gained lots of users and built a funnel worth $2 billion in 6months and is on track to hit $4 billion by the year.

I’m also barely even using AI to its potential. Now that it can understand and translate my ideas into form——literally what can’t be accomplished?

@Yuchenj_UW Yup and paid API usage on it all so really you need to start doing lawn service or plumbing

Same. I’ve built an AI fashion app, an AI short video app, and an AI prompt hotkey Chrome plugin.

So I’ve come to the conclusion that distribution is everything. Now I’m slowly building my audience on YouTube, where I talk about how to build and sell AI products.

Just finished editing a podcast episode with a YC founder on AI-native marketing, and it’ll be out this Monday.

@Yuchenj_UW this is the productivity metric we should actually be tracking — cost to produce trash dropped 67x, but demand for it didn’t move.

@Yuchenj_UW Most founders build, then look for customers. Do the opposite: get the customer, then build. Payment validates the idea better than any roadmap.

@sohocine ^ we should all think about this before building anything, even it’s easier to build anything with AI now

@Yuchenj_UW C'mon man, you can maybe build one app over the weekend with AI. Are you taking into account: adding app to the App Store Connect, making screenshots, testing, testing IAP purchases and subscriptions, waiting for app review?

@Yuchenj_UW I would build 1 useless app that is used by the 66 other useless apps. If AI is the producer, AI can be consumer too.

@ethankongee @Yuchenj_UW distribution is everything is the lesson that took us way too long to learn too. built stuff for months that nobody saw lol

@Yuchenj_UW That's not building man lol

That's fancy decoration with a domain name

Though I like the speed

When you build something for nobody, I'm not sure we can actually call that building in the plain realm of things

@Yuchenj_UW productivity hit a new high, zero progress unchanged

supply chain for unhelpful tools is thriving

@Yuchenj_UW the real innovation is the ratio of effort to zero users improving exponentially

@Yuchenj_UW The 68th app should be a swarm of million agents to get VC traction faking ORGANIC users. 💸💲
