You seem to conflate this with another issue with the demo: It was so good that it seemed real, and you deem this to be deception/deceptive.
While I may share some of your concerns, I can't help but compare it to the rants against video games: unhealthy, fake social interaction. Often used by politicians without any scientific backing of their claims.
I do understand the current attraction from the general public to the unsurprising AI research going on at top labs. You don't need any relation to the field to muse about killer robot singularities and 2000 year old ethics philosophy, and no one will brand you a fool like they did to the people warning about earth-eating black holes at CERN.
