From a strict growing perspective - HELL YEAH!! I've grown and still grow a wide variety of things from water lilys to palms, orchids to colocasias, corn to milkweed, and cucumbers to weed. Started in the 70's and have only gotten better ever since IMHO.
Growing cannabis made me transfer the skills I learned from weed to every other plant. Looking at growth, watching for pests, paying more attention to the growth patterns of each plant and especially the flowering/fruiting phase.
I was an adequate grower when I started (I usually didn't kill stuff), now I think I can pretty quickly figure out how to grow almost anything. Internet access surely helps the learning curve but you still have to apply the knowledge.
