I'm sorry no. This is simply wrong. Computer proofs are not there yet, and plus, a lot of the interesting theorems (including many of the well-known ones) are non-constructive which are difficult to prove on a computer. In fact, many theorem provers cannot prove 'basic' facts about math due to how constructive proof theory works. Indeed it is not clear what truth means at that level, but considering we regularly use non-constructive proofs to build things, I'm not sure that matters.
I think what is most undervalued is the utility of sheer competence and technical skill to creativity. Without the former, there is no latter. If someone who never studied piano told you they had a beautiful piano solo in their head, would you believe them? More importantly, would you trust them to execute on the creative impulse?
