I could go on for pages about the pros and cons. The TL;DR summary is approximately "both the presence and the absence of perfect secrecy (including but not limited to cryptography) are existential threats to the social, political, and economic systems we currently have; the attacker always has the advantage over the defender[0], so we need to build a world where secrecy doesn't matter, where nobody can be blackmailed, where money can't be stolen. This is going to extremely difficult to get right, especially as we have no useful reference cases to build up on".
