Blockchain is going to change everything and there will be a day when everyone is using it in one form or another whether they want to or not - it will be the money of the future and our children or grandchildren will be looking at how we trade or buy things in their history lessons ( proberbly not books by then). I think before that happens there will be a lot of scams which take peoples money, think of the get rich quick schemes now, well I think they will be on a grander scale and with the new technology which not everyone will understand I think it will be easier to scam and cheat people . Each new technology brings out the con men promising the world. It is sad that people still fall for it.
Kodak is a dead company. Over here nobody uses their cameras. It is all smartphones with digital pictures. Too bad the executives thought it wrong at that company. It turns out people do take pictures on their computers, might not be on the same scale but instead of giving up maybe they should have tried to embrace the digital pictures and offer a service geared at them ( although I am not sure exactly what but they pay people to give them those ideas )
