>"Is lines of code a good metric? Short answer: no." [...] Some of the most important jobs in an engineering team involve little code. They fine-tune configs, research arcane issues, and dive deep into underlying architecture. Working on these jobs can mean days of research just to make a few-line change. [...] I’ve personally worked on a few projects that touch these areas. The changes are sensitive, dangerous, and require a lot of skill to get right. If Elon laid off these small-code/big-impact engineers, then Twitter is in for a rough time."
