Nine years ago on a defunct platform I wrote this (and I made a big statement, now-deleted, more below)

What do you think of this explanation of the Hodge conjecture by Melbourne mathematician Arun Ram?

I think it's great: the right level of metaphor and concrete examples that arise from simple cases of the problem.

Last week I was asked to explain off the cuff the Hodge conjecture by a colleague who is an engineer of some kind. I had recalled from a more recent peep into a certain pop-maths book (mentioned in the [...] above) that the author kinda wimped out, leaving the Hodge conjecture for last and then admitting it was rather complicated. I think I was a bit harsh in what I said in the redacted bit. But that may have been because I don't have the expertise in writing for a popular audience, and this certain person very much did, and held themselves to a higher standard of exposition in both detail and clarity than I would have, nine years ago.
I'm also slightly cooler on the metaphor in the linked post — it's still a good metaphor, but it doesn't work so well for me now as when I first wrote the above.
