>1. Chrome beat Firefox in the stability/security area. Its usage of multiple processes, sandboxing, etc is excellent, while Firefox failed to adapt. Servo seems to have an excellent potential for coming up on top there, being both more secure, and having higher performance.
They did adapt, and the HN types got mad at them for breaking the old-style extensions, which were effectively incompatible with multiple processes, sandboxing, performance, etc. And were totally incompatible with Servo at a fundamental level.
>2. There are actually markets interested in security. Think say, banking, military, industry, IOT.
Those industries are infamous for doing things like having applications that only support IE9 in Windows XP. Security may matter to them in theory but in practice it is clearly far lower on the priority list than stability and supporting one golden path. Getting them to adopt something novel and experimental for use cases they want to be thoroughly boring and unchanging for 15 years is never ever going to happen.
As someone that compiled and ran Servo and submitted a couple of patches, it had a long way to go (years of development) before it would have been production ready in its entirety.
