I think smart contracts would make a lot of things in life easier for example you could do more things without a notary as most paper works could be stored digitally and uneditable in the smart contract and nobody could deny it as blockchain technology is not changeable... there are endless ways to use this new technology for a much simpler life but tho it would make some people unemployed and so they would need to do something else... still this was always the way to go, some people will benefit while others will lose.. thats life I guess.
