    As a general rule, if you need to improve a system by more than 3 orders of magnitude along some dimension, you're likely to have to rebuild it on top of a completely different technology stack altogether

        Would be interested in hearing examples of this in practice. I agree in principle, but I lack the experience to think of an example of this off the top of my head

        Good example: see blog post. “While historically Uber has been mostly a Node.js and Python shop, the Go language is becoming the language of choice for building many of Uber Engineering’s new services.”https://eng.uber.com/go-geofence/

        What dimension would that be? If you refer to performance, I have seen 10x performance improvements without rewriting, but through optimisation.

        10x is one order of magnitude only. 3 order of magnitude would be 1000x 1000x is not an easy task to achieve purely on optimization. It'll require scaling up and scaling out

        This assumes that the system already utilizes given resources fully and has minimized redundancy?

        Could it also mean that the system wasn't optimally built in the first place? Tech stack is a moving target anyways.
