That's not what I'm saying. I'm talking about 5 years ago when IE7/IE8 were lagging behind by a HUGE margin and it was another world trying to make things compatible. It was not a matter of using the last version, it was a matter of Microsoft not paying attention or not wanting to make its flagship browser better. Not just some developer throwing a fit because he needed "sugar".

Also, and that's only personal opinion, but there's a limit to the customer is always right. What if we create a new super highway one day with flying cars, are we going to punt on moving on because some people like their combustion engine pieces of junk? It's also our jobs to make people understand that jumping on the latest technology is in their best interest. Leveling the field to the lowest common denominator brings everyone down in the end and really hampers creation and innovation.

And that is the reason why Javascript is so far behind modern languages in so many areas.
