I've bluffed my way into technology changes every five or so years, across my career.
It went, for me, like:
Why do you want to do this, when you mostly have experience with that?
"It looks interesting."
Do you have experience with this?
"No. But I know how to read the documentation, I pay attention and ask questions when my colleagues explain something, and I studied the basics of this, in college."
It doesn't usually land me the job. But all I needed was an occasional "yes" here or there, to get started on something new, and expand my experience.
Plus, even the "no" interviews have still been good for my professional network.
