Yes, with better technology, it will be easy to create websites like Wordpress. This is what happens with any technology. However, in the case of complex problems, it is generally the responsibility of the engineer to divide the problem into smaller ones. Some people would say that web developers die slowly every day.
It seems that if a person wants to create a site, they can go to one of those sites and drag and drop to create a website. I very much doubt that, as users, we will give up the possibility of viewing data or video conferences through large screens. Web development is at the core of many real companies. Even app-based companies have web applications that they use for their administrators, moderators, etc.
Even app-based companies such as Robinhood, a stock trading application, provide web applications for users. To think that application development alone is sufficient is very wrong. Yes, it is in demand, people need to create websites and applications. Enterprise web engineering is never going to go away.
Wix is ideal for small businesses. It's ideal for family stores that need a website for their bakery. I am happy for them, I absolutely support them and often (as a freelancer) I suggest it. These sites will not destroy large scale web applications.
The reason behind this is that they are limited by their own internal programming. You can't have all the flexibility of an application. I think the barrier to entry for simple things, such as a marketing site or a simple CRUD application, will continue to decrease. But there are worlds and worlds of complexity that still need to be considered, in addition to all the legacy material that exists and works perfectly.
No Wordpress or Squarespace site will be flexible enough for anything more serious than a blog or small business page. There's a reason why large companies have enormous amounts of resources dedicated to infrastructure and web development. In fact, web development is growing even more in opportunities, and the expansion of fields such as IoT, AI, data science, machine learning, NLP and cryptocurrency creates an increasing demand for specialized developers with web experience;). I originally learned to program as a hobby, then turned to web development and worked as a frontend developer for a company that built websites for a while.
If you want to focus on things on the server side, maybe develop services for scalability, or do some specialized data processing, you might want to look more at the different relational and non-relational databases (MySQL is a good start for the former), in addition to the problem of scalability It will probably catch you. As for containers (for example, if you talk about web development in the sense of software engineering (creating web applications, not just basic sites), then no, the web developer is here to stay, at least for the foreseeable future.
