I, for one, have no desire for a voice-controlled home. What would be the advantage to me? It would just become another thing that needs maintenance and replacement. How often do you need to fix a light switch in your house? It's rare; it's a reliable piece of equipment. I've lived in houses with pre-WWII push-button switches that remained in service because they just keep working. Why would I replace that with something that needs firmware updates, security patches, and then eventual replacement when the manufacturer decides it's not going to provide support any more? Or, if it's open source, just becomes another abandoned project?
