Heh, I was agreeing with you, more or less, up til this post.
I don't think Python has "no chance", more that it will remain a niche product. Don't forget, Google are heavily invested into Python: a significant amount of their server-side code is written in it. That said, the popularity of Python frameworks like Django is still much less than Rails, and that itself is a smaller slice of the pie than PHP, so while I don't think Python will ever die off, nor do I think it will ever become as popular as Ruby, PHP or JavaScript.
I also don't think saying "Firefox will always have more functionality than Chrome" is the same thing at all as saying "Firefox will always remain relevant". You appear to be making the classic mistake most geeks make, in that you're assuming that functionality, extensibility and choice is what most people want. It's not. Most people who use the internet don't give two hoots about that, they just want to search on Google, read stuff on Wikipedia, buy stuff from Amazon, and maybe post on a forum or two. Simplicity and speed is precisely what they want. Most of them don't even know what a browser
is, and it's only through Google's massive advertising efforts that Chrome has any relevance at all outside the tech world.
As for Chrome's Dev Tools, well, I kinda prefer Chrome for my work over Firefox and Firebug, mostly because after a while Firefox starts pushing my CPU to 100% a lot even for simple things like DOM operations, and also because it's faster. There are a few things Firebug does that I sometimes need, and in such cases I'll use it, but mostly I work better with Chrome.
