Luckily you don't need any of these fad/new libraries to make good products and websites.
As I'm finding out. Two years as a system admin and not keeping up with trending tech and I can't land anything here.
In every other place in the world nobody give a damn about the latest technology. They only need something that work for they problems.

My local craigslist has dozens of jobs posted today looking for "Linux sysadmin" with scant requirements, offering $60-70k. Not huge money but better than being unemployed.
