I agree with your assessment, however I think tech executives are out of touch and lack self-awareness if they think people really want or need this. The whole reason an EA is worth it is because you are making outsized money and your time is worth too much to handle any mundane details that normal people deal with. Along with that there's the whole social signaling of having an EA because it signifies ones wealth and importance.

A free digital EA confers none of that—and it will annoy everyone you know. The only use case I see having legs is dealing with large bureaucracies like canceling subscriptions or medical billing issues, but there I think the common man will lose as the rise of this automation will see a distributed adversarial response from bureaucracies who will happily put up whatever barriers are needed to prevent Muse and other digital EAs from impacting their bottom line.

There's a 50/50 chance I'm just getting old here, but I really think we're going through an epochal shift where new consumer tech won't have the same reception as the smart phone and increasingly addictive bite-sized algorithmic media did over the last couple decades. I think going forward there will be more palpable questioning from younger generations about why do we even want some of these tech products? At some point convenience reaches diminishing returns and we have to think deeper about what we're trying to get out of life.
