They seem to have constructed a rocket with 10x the payload to LEO of the one they used to put those 10k satellites in orbit, and even demonstrated payload deployment. So I'd say 100k looks do-able for them today.
10x that seems aspirational, but not comically so. Folks hate Musk, but that seems to cause them to not see the engineering going on in front of them.
