If you accept the adage “the greater my sphere of knowledge, the greater my contact with the unknown” (I do), you can see how the author’s sentiment exists even as we age and even grow in wisdom and knowledge.

One of my realizations is that it’s harder to telegraph what you don’t know than what you do know. It’s easy to see that older people have journeyed the paths were on, and seem to “know what they’re doing.” In reality, what they know (to some degree) is what we (the less traveled) are experiencing. But they, having thought they were coming to the end of their journey, have found their is yet more to learn and sometimes pop up in moments like this to exclaim “guys, this journey just keep going! I still don’t know! Acquisition of knowledge and experience has no end game!” It’s humbling.

Great adage. It's from David Christian in Origin Story: A Big History of Everything, but really it's just a paraphrasing of Einstein, who compared knowledge to a circle, and referred to the circumference of darkness, rather than the unknown.
