Most of the developers I've met in Silicon Valley
What's the age range of the developers in Silicon Valley these days? I suspect they aren't old enough to remember *why* we needed web standards.
I'm a web developer and have taken JS & CSS for common for years and years now. Spent about 6y working at a small local web design shop and it just wasn't feasible to double contract amounts to make sites work without JS.
Sounds like a management problem, not yours. It is feasible to double contract to create JS-disabled fallbacks. Your company needs to address this in their proposals under accessibility.
This is not what Apple does. Safari has an option in the main preferences pane to enable "Show Develop menu in menu bar". For the past several years, Safari's developer tools have been the most advanced. Other browsers, especially Chrome, have mimicked their GUI and toolset albeit as a dumbed-down implementation.
This is clearly another case of too many mad scientists, and not enough hunchbacks.
