I definitely think authenticity or at least perceived authenticity will become more important in the future. There's a reason vacuum tubes are still produced industrially for guitarists and HiFi enthusiasts despite being over half a century obsolete and it's because despite digital modelling being just better from an engineering perspective people value the perceived authenticity of the real thing. I'm drawing up plans to build a valve amp myself, despite the fact it'll be worse at being an audio amplifier than one I can buy for a tenth of the price of the parts I value the gently glowing glass and straightforward analogue approach to amplifying sound.

I think whether AI content will put people off the web in general will depend on whether it's actually any good or not. 'That looks like an AI made it' is usually an accusation of shoddiness at the moment!
