I think it&#x27;s uncharitable to take Tran&#x27;s interesting story and turn it into a criticism of him for not working on &quot;harder stuff&quot;. You didn&#x27;t phrase it that way, but it follows from what you&#x27;re saying, and that&#x27;s unfair. A person with his background is as free to work on what motivates him as anyone else is.<p>No one would disagree that &quot;harder stuff&quot; is important, but the trope of using this in arguments to belittle what others are working on comes across as finger-pointing. On an actions-speak-louder-than-words level, few of us are in a position to judge others about this, and I have the impression that those who are, tend not to.
