They are very similar actually, but permaculture is about more than just agriculture, agriculture is one of the sides of permaculture. For me syntropic agriculture is that side, some people also call it agroforestry but this term is used for other kinds of agriculture, which builds forests but differently. On syntropic the main difference is very high density of plants and extensively pruning. The video I posted in the first comment you see a few people doing research on automating this processes, there's also some people Swiss investing into this, sure with less biodiverse but its being working great for them, so yes, can be automated, also lots of machines used on fruits crops can be used on this system, specially to speed up pruning bigger trees. And usually on syntropic its not common to find "key" shapes beds and stuff that we see from permaculture, its usually straight rows, which helps a lot with automation I guess.
