I believe it's not really that frontend is more complex than backend. It's a matter of maturity.

My work involves more FE than BE nowadays and I do think FE is more challenging at the moment.

But it's mostly because all these problems are very new. FE never used to store a lot of state. Now that interactivity is expected, we do. Users expect polish so we add transitions. As we add more things, performance becomes something to keep in mind, and so on.

In a decade or so, I think these issues will be very trivial to solve. Standardized solutions will emerge. Browser support will get better and JS will improve (hopefully). We'll be solving entirely different class of problems.

It's what has happened to BE. Nowadays you can expect an ORM, a cache layer, and queue systems among others to be standard to any BE installation/framework. The traditional RDBMS in itself is a sight to behold. Imagine working on BE before these things became the default.

Many things are abstracted and a lot of people aren't even aware of them. For example, I don't know when's the last time I heard about SQL injection. They are all automatically handled.
