I planted one of these trees a few years ago and I think it's absolutely gorgeous. I can't get over how absolutely huge the leaves get. A lot of people hate them though, for the same reason outlined in the article: you can't kill them. Many consider them weeds.

I think this is a neat idea but have one question. I'm not a chemist but am curious what happens to all that carbon after it's taken in by the tree. Does that carbon become something else? Or does it just kind of hang out in the tree until the tree dies? Once the tree dies, does all that carbon just go back to the atmosphere again? Thanks for any insight!

Yes, it's only captured until the tree dies. After that the tree rots etc and carbon is released again.
The clue to net carbon capture is to plant new forests and make sure the forest stays alive. While the forest lives, all the CO2 is safely sequestered.

The carbon becomes part of the wood of the tree. After the tree dies, it would only go back into the atmosphere if the trunk was burned.

If you're trying to do carbon capture, maybe this is a feature? Assume you mean that literally, and you can just chop one down and another will grow in its place, that's pretty great, since trees only capture carbon when they are growing.
Forgive me, but it doesn't look like much. How can a tree with such a small mass contain more carbon than a massive tree with trunks and branches? They don't even seem to be very close together in those photos: https://www.bloomberg.com/news/features/2019-08-02/we-alread...
If you don't cut them down the first year, they become decent sized trees. However, it isn't about total individual tree size. It is about the fact that they trap more carbon into wood tissue per year, because they grow so very quickly. An oak may take 20-50 years to reach the size an empress tree will reach in say, 5-10 years. Therefore an oak traps carbon far more slowly. Oak is stronger, nicer, harder wood, because it grows more slowly, but also captures carbon more slowly. Different growth habits, different speed, from different ecosystems, with different uses.

It turns into wood! It's actually pretty amazing. I always though the physical substance of wood came out of the ground, through the roots, but in fact wood is made almost exclusively out of air. Trees are frozen air.

It's not about carbon per tree. It's about carbon per acre*year. Dense woods grow slowly so they take in very little carbon per year even though they grow very large. Fast growing trees are much better at quickly taking CO2 of the atmosphere.
Fast growing matters. The ability to harvest them and have them regrow matters a lot too. That’s what makes bamboo so effective at carbon capture.
