what I mean is: building these systems is nontrivial, but if done well it can help. Imagine non being in an endless queue on a phone call when having to do a simple task through a customer center call, or having a phone reminder with more information and less noise than from a written notification. The fact that I failed at it (for lack of experience and resources) does not mean it should just be shrugged off as useless or impractical. Some companies offer this service and it works just fine for narrow use cases.
