What work do you propose?
The reason why the like of Branson and Musk state their positions so clearly is because they know that the jobs are going away. You want to tie it into work...so are you going to mandate jobs be created just so people have a place to go to "work".
That is actually what we did in the west the last 20 years to a large degree. We created a great many bullshit jobs just to keep people employed. Now, corporations are wise to this game and realize their profits are much greater with less employees. AI and other forms of automation enable this.
Not work for the sake of work... But I think that with every new technological cycle, people have predicted the end of work, the end of jobs. I see the blockchain as ushering in "a new Internet era". The original killer app for the Internet was email. Then came the graphical user interface. Then people started building companies, entire industries, around the Internet. I see the same thing happening with the blockchain. And that's why I'm so optimistic around the idea of SMTs for Steemit. The Internet era was all about digitizing everything that could be digitized (books, music, financial assets, etc.). The blockchain era will be all about tokenizing everything that can be tokenized.
I do understand what you mean but do search on youtube: Humans not need apply and watch the complete video. Maybe this will change your mind. The revolution which is coming towards will have a much bigger impact than the industrial revolution.
