As a matter of fact, AlphaZero already plays more aggressively than typically expected of chess engines. Eg. in a well-known game it beated Stockfish (the strongest traditional chess engine), brilliantly sacrificing 3 pawns for a non-obvious, human-like compensation. This once again challenged the notion of what the perfect play boils down to in chess. Oversimplifying a bit, it had already been assumed that it's solely about grinding the opponent down by mercilessly accumulating miniscule advantages, while all the flashiness only worked because human players are error-prone. As it turns out, it may have been just another limitation of chess engines as we knew (and built) them.
