Sure, but to me, ALL human-invented notions are subject to interpretation and change over the times.
We had kingdoms, slaves, and eye-for-eye punishment before and we largely don't have those concepts today in the developed world.
The same is true for conflict-of-interest, fiduciary duty, and today's version of capitalism.
If I had said "we don't need slaves" 400 years ago, I would have been downvoted like crazy. And here I am, saying conflict-of-interest and fiduciary duty will be antiquated ideas, and I'm being downvoted here today. Let's have an open mind about the future, shall we? I'd rather in a community like this we put everything we blindly assume today on the table with an open mind and discuss how we can change or improve the system.
On a related note, AlphaGo is able to play against itself using a single CPU/GPU, and it gets better by doing so. Why can't a human play against itself and get better as well? Are we brainwashing ourselves into thinking we are unable to do that, and so we are not trying?
