I am wondering, what sort of tasks are you seeing these x20 boost?
I scoped out a body of work and even with the AI assisting on building cards and feature documentation, it came to about 2 to 4 weeks to implement.
It was done in 2 days.
The key I've found with working as fast as possible is to have planning sessions with Claude Code and make it challenge you and ask tons of questions. Then get it to break the work into 'cards' (think Jira, but they are just .md files in your repo) and then maintain a todo.md and done.md file pair that sorts and organizes work flow.
Then start a new context, tell it to review todo.md and pick up next task, and burn through it, when done, commit and update todo.md and done.md, /compact and you're off on the next.
It's more than AI hinting at what to do, it's a whole new way of working with rigor and structure around it. Then you just focus fire on the next card, and the next, and if you ever think up new features, then card it up and put it in the work queue.
If one of these things isn’t true, you’re either a fool or those productivity increases aren’t real.
A simple example: if someone patents a machine that makes canned tuna 10 times faster than how they're currently being made, would tuna factories make 10 times more money? The answer is obviously no. Actually, they'd make the same money as before, or even less than that. Only the one who makes such a machine (and the consumers of tuna cans) would be benefited.
10x to 20x is in relation to time, so something that would have taken 2 weeks (80 hours) would be done in 8 hours to be 10x.
> Do you clock off at Monday lunchtime and spend the rest of the week playing video games? Did your boss fire nineteen developers and give their jobs to you?
In other words, how are you taking advantage of all that extra time you claim to have?
Claude code has made bootstrapping a new project, searching for API docs, troubleshooting, summarizing code, finding a GitHub project, building unit tests, refactoring, etc easily 20x faster.
It’s the context switching that is EXTREMELY expensive for a person, but costless for the LLM. I can focus on strategy (planning features) instead of being bogged down in lots of tactics (code warnings, syntax errors).
Claude Code is amazing, but the 20x gains aren’t evenly distributed. There are some projects that are too specialized (obscure languages, repos larger than the LLM’s context window, concepts that aren’t directly applicable to any codebase in their training corpus, etc). But for those of us using common languages and commodity projects, it’s a massive force multiplier.
I built my second iOS app (Swift) in about 3 days x 8 hours of vibe coding. A vocab practice app with adjustable learning profile, 3 different testing mechanisms, gamification (awards, badges), iOS notifications, text to speech, etc. My first iOS app was smaller, mostly a fork of another app, and took me 4 weeks of long days. 20x speed up with Claude Code is realistic.
And it saves even more time when researching + planning which features to add.
There should be a FOSS project explosion if those numbers were true by now. Commercial products too.
Jokes aside, if 20x was on the table for any kind of meaningful work we wouldn't need to wait for much of anything, entire parts of industry would be invented and technically reworked by now. It's most likely ~1.25x for what is mostly trivial work that approaches 95% boilerplate and zero actual design work.
If you read calrain's posts the 20x number is taken from the "fact" that sometimes (not consistently or most of the time) something that was estimated at 2 weeks or 80 hours (who knows what it was and how that number came to be?) took 2 hours instead. That's not just some minor detail; it's just not a sound way of thinking about productivity increases.
Words without actions are junk. You are asserting something you have no proof for. Proove it then. Amaze us all with your productivity, out in the open. Shred those pilled up open issues on open source projects and then give us a report of how fast-easy it.
If it is "easily true" you'll be done by next month
But I agree, you don't need to prove anything to me. You need to proove it to yourself first.
