@taskmaster4450 - this is another quality post with impressive content. Bravo - upvoted! I had not thought about where Steem and other cryptos fit into the grand scheme of things. You put this in perspective for me. You are correct the nature of work is changing, I would categorize this as "transforming" from one form of work to another. Going from an industrial to service (all based on labor as you said) into an informational/digital work.
The content that's produced on Steemit is every bit as valuable as manual work and even more (I haven't yet seen much ROI yet on Steem, but I am sure I will soon). Keep up the great work- Resteemed!
