we told claude code + sonnet 4.5 to rewrite our entire typescript repository in go it ran for 29 hours results below:

none of it worked

@marsxiang_ I think @ishaandey_ could do it in 15 mins ngl

@ElijahKurien @ishaandey_ @ishaandey_ welp now you know what ur next task is

@marsxiang_ typescript is not a one-one replacement for Go both are built to solve entirely different problems Typescript is to help your build better frontends (UI+API) Go is to help you build thread and memory safe concurrent applications or services with more common use case for the

@marsxiang_ Guessed this :) llms became a joke

@marsxiang_ AGI is coming but it still needs coffee breaks.

@marsxiang_ Claude basically said: โ€˜Have you considered rewriting your repo in vibes?

@marsxiang_ claude code needs an anthem

@marsxiang_ blog post coming soon

@marsxiang_ YOLO goons. There is SO much you have to know to perform a replication port. You have to deconstruct the original codebase first. Iโ€™ve done this SUCCESSFULLY with Claude Code from Typescript to C# on a large codebase. It required ME to know how to perform a proper sequence.

@marsxiang_ 29 hours!? sounds like you're broke now because of anthropic pricing

@marsxiang_ Pay me instead. I can write a library that doesn't work in half that time.

@marsxiang_ bait but also kind of a banger?

@marsxiang_ that was never supposed to work

@marsxiang_ still its too good for small changes or features. btw did you check with gpt 5?

@marsxiang_ how about gpt 5?

@marsxiang_ Results: 826849 typescript build errors bc Claude always uses โ€˜anyโ€™ type

@marsxiang_ just ask poke next time

@marsxiang_ ๐Ÿ˜… how much did that cost too?

@marsxiang_ this is why I m still using 4 sonnet.

@marsxiang_ oh wow, that was fun. โ˜ ๏ธโ˜ ๏ธโ˜ ๏ธ

@marsxiang_ i believe ai is great for small tasks but full rewrites in different languages seems like asking for pain

@marsxiang_ Nice bait ๐Ÿ˜€

@marsxiang_ I can do it in 28

@marsxiang_ I was ready for that twist and still got me

@marsxiang_ 29 hours huh?

@marsxiang_ only 29 hours?

@marsxiang_ had me in the first half ngl

@marsxiang_ big bait

@marsxiang_ That's brutal!

@marsxiang_ big mess?

@marsxiang_ When the bill arrives

@marsxiang_ ๐Ÿ˜‚๐Ÿ˜‚
