Agreed. As someone who works in AI (and knows its limitations) it's frustrating to see the layperson getting nervous about AI after watching Chappie and hearing some of these quotes from Gates and the like. Human level AI is way way way out.
Imagine the public sentiment if mass media made people aware of the inevitability of the nuclear bomb 50 to 200 years in advance and people (not just the government) were actively working on developing it.
I think that had nuclear physics been more obvious 50-200 years earlier, it may have lead to a lot more practical private-sector development. In the case of power generation, this is seriously beneficial.
How will private-sector AI turn out? Will they boot up sentient AIs in Docker, then discard them? Is that OK? Who even knows?
