Here it's obvious what's going to happen without robust legislation protecting the likeness of all individuals (and not just special-case celebs) from the non-consensual generation of new material.
The fact that such legislation is unlikely to happen before an awful lot of suffering has occurred is a testament both to naive belief that everything new is good. And to legislative processes with a bandwidth from the age of sail that is riddled with vested interests to handle the downsides when scaling breaks the happy path assumptions.
Focusing efforts on the legislative process seems likely to be more productive than point solutions that rely on techies and scientists not to develop tech that can be used for nefarious purposes.
