This is almost as long as the Earth has existed since its formation. It is an extremely long length of time. Suffice it to say humans will not be around anywhere close to that time. Nor will any currently recognisable life. All current species and families would've drastically changed and evolved into other forms, with the exception of simple, unicellular life. And of course around this time our Sun will be on its way to a red giant so the Earth would be becoming well nigh inhospitable for life (as it exists now). As for intelligent life, I don't think intelligence can remain stable for such lengths of time.
