Is AI set to replace personal assistants?

How did you go about creating something that works so well? I can't imagine that your first version of this was such a smooth transaction for users. We had a few truths that we believed in where we've designed the product with these as the backdrop from day one. The first one is that we want this to be invisible software - we don't want this to be yet another app, a plugin, an extension, a web service, a Doodle, a something where you have to do additional work. We wanted something where we see software disappear and you hand over the job to that agent and that agent runs away, works on it and comes back once solved. That was the first battle.
