>> If it's boring technology, why be excited about it?

Surely, on Hackernews, we know we can get excited about technology that maybe boring to most of the public. And in this case, I think the technology has wide-ranging productivity enhancing applications

Maybe your question is about why the tech billionaires are trying to get the public so excited about it? Totally different question.

>> It will still be same 8 hours of doing something

Yes but your 8 hours of work will serve more people. Will you see the fruits of that productivity gain? Very good question, but again, orthogonal to the usefulness of the technology.
