I did not mean 100% of houses will be hacked (as your stupid rhetorical question tries to imply), but given that all your appliances, electric grid, your car, etc. will be online, the incentive, the probability and potential damage of a hack will increase.
You must be one of those who said Wifi passwords would never be stolen, naked celebrities' pictures would never be leaked from supposed "super secure" servers, ATMs would never be hacked by 14 year old teens, entire gaming networks would never be taken down by attacks, millions of passwords of Facebook users would never be exposed, phishing and banking fraud would never cause millions of dollars of losses a year (which they do), etc.
You seem to be the typical smartass that oversimplifies things with pre-manufactured responses. Thinking a little bit before posting would do you good. Try it.
