I'd say it's the easiest to learn without a formal qualification, and the easiest to learn just by watching YouTube/video tutorials/doing a bootcamp etc. Learning embedded programming, OS design, compiler design etc. is much harder without actual experience or working with people skilled in the area. Sure, can be done, but much less people attempt it. So I'd say that just from that perspective, there is a lower barrier to entry, and therefore more competition and less job security as a front-end dev. Doesn't mean the right job won't pay well, but I think you'll find in the coming years, many more people will be passably competent in front-end web design.
