I disagree with the claim that its sticky, but this is the wrong response. Reductive and doesn't take into account the obvious things (UX, network effects, barrier to entry to use the product). All 3 of these are much better with Muse than they with are similar products.
UX is not a moat, especially in the era of AI software replication. I disagree that there are network effects for MUSE, maybe there will be at some point (e.g. vendors or something sign up for it) but I would love to hear why its better to be on muse when more people use it? Barrier to entry is somewhere they have an advantage, but not more of an advantage than google, or really anyone who has an app installed on your phone already.
