(1) More tech doesn't save time if it's developed in the direction/dimension of more information flow. Because it seems that the best environment for creativity is a somewhat restricted environment of information. And if one needs to engage with information to take advantage of this new tech, it actually impedes creativity.
(2) A lot of the grunt work that we seem to be automating also encourages creativity. From what I've observed from many artists and programmers (I hang out with both), it seems that creativity strikes best when it's not forced, and the "downtime" doing grunt work actually accelerates it.
So I think that AI breaks these two principles (minimal information and the removal of the crucial grunt work), and actually makes us work more for less.
The only gains seem to be those short-term kinds (a program can be made faster, rewards can be reaped by senior people who have thought about stuff for a while), rather than encouraging a healthy environment of creativity....
