It's a completely pointless tool.

It's a completely pointless tool. First, google provides a link to always loaded the latest version of jQuery, thus making this library redundant. But more importantly, methods and variables in jQuery get depreciated. If you auto update, it could break your code. It's important to always ensure the version of jQuery loaded works with the code being used. Thus, you should only update manually, ensuring compatibility and never problematically load the latest jQuery version.

Thank you for your opinion. But first of all class is not intended for automatic update, but check and then if you want to update eg for CMS. Does it means if load the latest jQuery version (using link) from google it breaks your code? I would not agree with that, and that is a similar thing.
