I don't think that the current popularity of 1.d4 is due to playing against computers. The main reason it is currently more popular than 1.e4 at the highest levels is that Black has found a very effective way to counter 1.e4 (the Berlin variation of the Ruy Lopez) that makes it difficult for White to achieve more than a draw. This high-level popularity then trickles down to lower levels.
It is definitely true that the style of play has changed somewhat due to computer engines, but it's not so much the result of playing against computers (top players generally don't find that very rewarding), but of analyzing with computers. You can play through a game or an opening and explore variations, with the computer constantly telling you what it thinks the best moves are and who is winning by how much. As a result, players become trained to evaluate positions closer to the way a computer would. One example is that computers don't mind grabbing material and defending an unpleasant position for a long time if they don't think that the opponent can break through. This has given players confidence to be more materialistic than they were in the past.
