I do think that "yo, look at my pumping out 10kloc/day" brags are quite stupid, because it simply does not take that many lines of code to support a large, profitable product. I'd love to hear other people's experiences here, but I'd say that a product with 100K-500K LOC can support a profitable company of dozens of people and generate tens of millions of revenue.
Now 100kloc is roughly 1M tokens, which cost a few dollars, so how could something that costs single digit dollars possibly be worth tens of millions in value? Clearly there's a substantial gap between how useful different pieces of code are, so bragging about how much of it you produce without telling me how valuable it is is useless. I guess it's a long-winded way of saying "show me the money"
