Its 'production' code because its a small browser game which has very small to 0 requirements on security and being perfect but high requirements on 'ever even doing this' and 'fun'.
The code it generated hat 0 compiletime errors. I was able to descripe 10 things to do in one task and it just jugged along solving all of them.
This doesn't need to become so much better to be useful. Its already very useful for a lot ofuse cases like researchers which have to verify the math anyway but are not good in writing code for filtering their testdata, converting them and running it.
Small websites, fun projects, helper tools etc.
But while we speak, in the background stuff is still happening left and right. More compute, better algorithm, more RL etc.
We could already be at 95% at 'ai will take your coding job' without knowing because these 5% are so relevant.
