To be fair, "star dust" is not rigorously defined, and the cosmological definition of "dust" includes some pretty big chunks. So after the sun swallows the earth, there's a very good chance we'll qualify. :)

Also we are more patterns in the dust given that most of the atoms in our bodies swap for new ones over a couple of years. The patterns may be able to continue separately from the dust.

At the cosmological scale, stars are dust.

I thought that at any scale, that they were atoms. Or quarks. Or quantum fields. Or whatever.

A dense ball of _everything_.
