I disagree web dev has always been entry-level. When I called it an entry level position, I meant only because the barrier to learning web development is lower than the barrier to get hired as an embedded C engineer or a backend API developer or a distributed systems dev. But there are plenty of very senior engineers that specialized themselves in web and are paid appropriately for their contributions. And in some cases the web component is the most critical component to the end user and requires very senior web devs to make it work properly.

I agree not to get caught up in the idea one developer specialty is better than another, they are just different and have different complexities.

In the end, the OP learning web dev is a great lower barrier way to enter the market and learn and find what they really want to do/build.
