its a few years since I read Liu Cixin's books and even longer since I read Greg Bear's, but the technology was very different, and it was not as uniformly hostile. The primary technology used to destroy civilisations in Bear's books was self-replicating machines, and there was an advanced civilisation that tries to defend or rescue those attacked, and punish the aggressors - so its a bit less bleak.
