> Quality of code has never had anything to do with which products are successful. I bet both youtube and facebook's codebase is a tangled mess.

This is such a bad take and flat out wrong. Your ability to deliver and maintain features is directly impacted by the quality of the code. You can ship a new slop project every day if you like, but in order for it to scale or manage real traffic and usage you need to have a good foundation. This is such a bad approach to Software engineering.
