I could produce way more than 1m lines of code in far less than a month, and wouldn't even need Copilot.
I'm actually a bit terrified of the amount of code being cranked out. We worked on some code generators yesterday (not vibe-coded with AI, but yes, AI assistance was used heavily throughout) that generated thousands and thousands of lines of code. So we looked really really productive yesterday...
My sub-contracting/consulting career started 20 years ago writing code generators for SharePoint. Using the WSDL to generate DTOs and Service/Repository classes for them to power brochureware websites for a large luxury rentals firm. When we got a new customer that wanted a similar setup but they used WordPress, I then modified that generator to work off Custom Post Types. It could output to C# and to PHP.
The customer never used the tools, my bosses never used the tools, they were for me to work more efficiently.
