i hope the tech will one day make slaughtering animals for meat a social taboo
like remembering the times before we had toilet paper...
However, the tech alone isn't even close to what's needed, remove mead subsidies. make it so it's a one every few days meal (like it used to be), not the core part of every meal.
also increase animal welfare regulation, so animals suffer less.
that will pivot farmers from meat production, and animal feed production to produce. we will need much less land to cultivate, so rewild them. IE, just abandon them and let nature reclaim it.
