No, I do not think they created wealth. These are great innovations that make life easier, but they do not create wealth.
Here's the thing: Money does not exist; bear with me, answers like 'then give me all yours' will be treated with the disdain they deserve. Money is trust, faith and force. I have a tenner in my pocket and you accept that for goodsandorservices (Thank you, Anyanka) believing that when you pass it on to the next person they will accept it at a fixed value. I have faith in the currency and it's backed by force, meaning if someone tries to claim my cash as theirs, it will be defended by force, usually from the government that authorises the issuing the notes. When the faith and trust go, you get a crash, much like Germany before the 2nd world war. Resources the day before the crash were the exact same, and everyone had just a day's more food in the cupboard and a day's food in their bellies. Did the wealth disappear or did people simply stop believing in it?
Wealth is like thermodynamics: You can't create energy or wealth out of nothing: All you can do is take it from somewhere or even somewhen.
