Chance of my house having a working electricity supply for the next 10 years, free from major defects and security holes, given that I pay my bills and live in a major metropolitan area: 99.99%
Chance of a Revolv IOT Home Hub working for the next 5 years: 0.000% this has literally already been shut down.
Caveat emptor.
No disagreement with you, but note that electricity used to be that way everywhere and still is in some places. People adapt their level of technology dependence around it. Over time reliability increases dramatically. Likewise early smart phones used crummy network capabilities, but a feedback mechanism drove improvement in the network which drove increased dependence which drove improvements in the network... the same will happen on the home networks.
It's not like we'll all wake up Jan 1 2019 and have nothing but cloud-connected home appliances. It'll be an iterative process, and slower than phone/VCR adoption because fridges and the like are slowly-replaced so-called "white goods".
If the electricity or gas has an outage, I'm not locked out (or in).
It probably already relies on the “electric cloud” and perhaps the “ gas cloud” already so what makes a dependency on a “computing cloud”any different?
