I have done both over the years. I started out primarily frontend but have gravitated towards backend. I try to keep up with frontend, but it does change very quickly. To your point, backend changes far less frequently, but it does change. I feel like its slower pace of change makes it a more sustainable career path. Time will tell. A lot of people are saying they’re similar in difficulty, but I believe backend is simpler largely because it’s easier to model. You have a much simpler more defined picture of these are my inputs, this is my output. You also have control over the exact environment your software runs under. Frontend often feels less like a science and more like managing chaos. Backend just has so many less variables outside your control overall. I feel like backend can be a little thankless at time, at least from outside. People care a lot more about some new widget than the transparent background changes that took months to roll out seamlessly and kept the whole thing running.
