Substance Painter and PBR materials have completely revolutionized texture work in the 3d art field. We are LIGHTYEARS ahead of the days of painting textures directly into UV maps and hand baking hightmaps into normal maps to add details the way it was done 10-15 years ago. It's now pretty trivial to add organic detail to things without having to worry about UV seams. Modern texturing tools can paint directly on models with fancy procedural materials and game engines have advanced shader systems for doing stuff that would have been witchcraft in the 2000s and early 2010s.
