He was mostly interested in how exactly to develop a creativity trait, and came up with something called a "Theory of a Creative Personality Development", a further generalisation of TRIZ.
There are some anecdotal confirmations from various schools across the former USSR that this approach is known to produce some stable results. So at least it worth looking into.
There are just people who somehow know the creativity tricks (either deliberately learned or randomly discovered), and the "ordinary" people who happen to have a little gap in their education. Learning the formal approaches to creativity could help to close this gap.
Secondly, if simulating creativity is indistinguishable (by the outcome) from a "true" creativity, then the very existence of creativity is questionable, and it is likely that all forms of creativity can be explained by simply knowing (maybe subconsciously) a number of techniques of "simulating" the creativity.
