Google Keep: Will it be closed by Google like Reader?

Google Keep, a Evernote competitor from Google, was launched. The UI seems good, as well as the features highlighted by Google.

However, I'm not willing to try it, or at least I will not really use it. Why? Let's recall Google Reader. Reader has good UI and good features too. But, Google closed it because it can not bring profit to Google. Google Notebook, a lightweight version of Google Keep, indeed is just another widely used product closed by Google. If now I transfer my notes to Keep and start to use it as my notebook instead of Evernote, what can I do if it is closed by Google some day?

Google has lost its faith.
