Uber is barely 10 years old. They can get away with this. Wait until it's 2 or 3 times that age, and its (present or future) regulators sign new laws into place that require massive changes or reporting feeds across multiple systems engineered and documented in this unprincipled fashion. Probably after a couple more privacy breaches or self-murdering car incidents. Nobody will be able to figure out how it all fits together, and the compliance team and auditors are going to throw a fit.

That's when all those architecture processes, repository tools and languages suddenly make a lot more sense. Uber deals with extremely sensitive personal information, and the move towards self-driving cars means they deal with highly safely sensitive systems. The dismissive attitude towards these tools in what should be a highly disciplined engineering organisation disturbs me, but I come from a highly regulated environment so perhaps I was just raised that way.
