Tons of devs (CS grad devs that is) have made their career writing basic CRUD apps, iOS apps, or python stuff that probably doesn't scratch the surface of all the CS course work they did in their degree. It's just like everyone cramming for leetcode interviews but never using that stuff in the job. Being familiar with LLMs today will give you an advantage when they change tomorrow, you can adapt with the technology after college is over. Granted, there likely will be less devs needed but the demand for the highly skilled ones could be moving upwards as the demand for this new AI tech increases
