I do know someone who finds Alexa or something similar quite useful. Some after effects of what started with an accident left him finding some previously routine tasks quite difficult. I believe it does help him with things like organising his day.

I think in previous days, he, like me would have been more likely to have looked for something probably along the lines of a caldav/carddav server on his own Linux box as a solution to calenders and tasks but he's finding he has to go with the ready made solutions now.
