Whenever someone complains about having to support different browsers, or a page says "this feature is best viewed / only available in browser X", I don't blame them! Would it be really bad if all browsers adopted the same engine and built their features on top of it? I also believe collectively we can make that engine even better.
(off topic) This made me think of logs.. there are so many different standards/formats out there, making log collection and parsing a nightmare. I think logging is something that's truly been cursed by its diversity, and something, if we worked together to standardize, would make this world a better place.
I think we could all benefit from more things being standardized, such as a social network protocol, a standard for self-driving cars so they are able to communicate and coordinate among each other, a browser engine like Chromium etc. Wishful thinking?
