I feel silly for saying this, but it's very obvious that rule breaking is not the same as acting immorally.
Machines should be able to speak in realistic voices. Every cool future I can imagine includes that. Why muzzle it just because people can be scammed with it?? People get scammed by jpgs, random people calling and saying they're from the bank or the IRS. I'm really not interested in limiting what humanity can accomplish to account for folks getting scammed. Many of them will get scammed anyway. What we should do is make it easier for these individuals to learn how to not get scammed or to come up with scam insurance for the ridiculously gullible. I'm just spitballing, but banning cool technology because people can be scammed is overkill.
