please, please more of this. silicon valley seems determined to produce more things that fall in my bucket of "stuff my mum used to do for me" - uber = mum used to drive me places, disruptive laundry, shopping for food, buying clothes... i'm not even sure if i'm half-joking.

Makes sense. As more of the population ages, needs technology, lives longer but is also still interested in using technology, catering to this market will be both necessary and useful to companies.
