The [question][1] was deleted by the post author, is thus generally not viewable, and I believe will fully vanish. My feedback in comment reads:
> Sorry, but _"How important is the DAG data structure to the future of our world, given that it seems to be central to technologies which are revolutionizing it?"_ is opinion-based, and only distantly related to cryptography. Mind you, a concept being used in cryptocurrencies does not make it related to cryptography; which is our only subject. Please make this a factual cryptographic question, or remove it. See this [meta on cryptocurrency-related questions](https://crypto.meta.stackexchange.com/q/985/555).

Proof by example of what's asked in title, and of the disputed assertion: the concept of _currency_ is related to cryptocurrencies; yet it's not related to cryptography per a [common definition](https://www.merriam-webster.com/dictionary/cryptography).

Alternate argument, admittedly using mathematical terms out of their charted territory: "related to" is a symmetric but often non-[transitive](https://en.wikipedia.org/wiki/Transitivity) relation.
