Yes, I agree.

These demos will have the dual effect of nullifying FUD while also 
shedding light on the real technology advances inherent in the 
architecture of the world wide web. Ultimately, we are always going to 
end up showcasing the fact that most are still failing to understand 
that "deceptively simple" != "simply simple" . In addition, there's 
inherent futility in undermining the intelligence and ingenuity of the 
human mind, thanks to temporality and cognition.

Yes, we will certainly be showing up with interesting demos along these 
lines. That includes some interesting UI elements too :-)
