Do full stack developers exist in this era?

I personally feel that both Front-end and backend have more stuffs to learn individually.

As a front end developer, I can get into the backend source code and do some minor changes for me without depending on backend devs. This doesn't mean I am a full stack dev.

Backend devs must have good logical skills and algorithmic approach towards solving a problem, when compared with front end.

Guys can you please share your thoughts?
