It is unlikely they will get radically worse, but its possible they won't get radically better.

However, on-the-hoof meat production has some ideas which can be remarkably transformative: the seaweed additive would reduce methane burp burden immensely.

Nothing much alters the water burden of different organisms. Beef is high. Almonds are amongst the highest in plant foods. Sustainable fake meat will want to be significantly lower than Almonds. Its already significantly lower than beef.

This has been an idea for years and afaik there is only one farm in Australia feeding their cattle seaweed. Keep in mind it is a specific kelp and to supplement the diets of the world cattle population with seaweed it would need to be farmed with exponential growth to the point of being a major or close to major crop.
