IMO with voice talent it's pretty obvious the AI will eventually win, especially when it pertains to video games where projects can contain 1,000s hours of dialogue. There's disruption right now because studios are being nice / have talent locked into existing projects that's hard to recast/pivot from. IIRC the voice acting drama also has a transnational dimension, something about blacklisting international talent from union projects if they don't join/pay dues to a US guild, which sits wrong with me. Either way the consequences of ceding to unions is bad for consumers, at least in video games. I don't want smaller projects to pick between either having all union voice acting and no AI which may be prohibitively expensive / not possible depending on scope. I want amateur RPG makers able to make projects with accessible AI generated voices, especially with how fast they're improving etc.
I don't know who will win, but it's not like these choices are not without consequence. These moves definitely slow down their plans.
