In my home country we have this story: a person goes to the doctor and complains "Doctor! It hurts when I touch my knee!" to which the doctor replies "then stop touching your knee."

Contrary to popular belief you won't be left behind if you don't use these "agents". If they ever get good enough that they don't need babysitting anymore and make you 10x productive, then you can simply adopt their use then. Any current skillset regarding prompting won't stay relevant.

Though I will caveat that I work on more niche subjects, not frontend, so my perception of their usefulness may be skewed.
