What makes it hard, these days?

I did plenty of WP back in the day and I agree, historically, but each of the strong answers I had in my mind (db integration, editor, plugins, themes) are weakened substantially by the AI agents' ability to port a working site to a new framework. I totally agree for normal users still but for devs taking jobs on this do you think the barriers to switching have come down in size?

its getting buy-in, especially from people entrenched in their workflows, convincing management and sometimes legal depending on what plugins are being used.
