What's naive about it? If you look at the accelerating rate of change then there is no indication whatsoever that it's going to slow down.
I think you're confusing the technological rate of change with the societal/cultural rate of change.
No, they're both moving at massive speeds and one fuels off the other. It took one hundred years between the abolition of slavery in the US and allowing non whites to vote, and then less than 50 years from that for a non white person to be president. That seems to be accelerating societal change to me.
