All physical objects degrade with time. Factory-pressed commercial discs like movies have an expected lifespan of 10-20 years assuming they’re stored properly at all times.
I am not an optical disc expert, but I recall with CDs/DVDs, factory pressed are more resilient whereas burned discs can rot more easily. I believe this still holds true with BR. Furthermore, there are carbon-based BR discs that profess to not exhibit data rot for 1000 years.
I thought disc rot wasn’t a thing anymore with Blu-ray?

Depends how you store them.
That and the quality of the disc. There used to be a manufacturer grade rating for the CD/DVDs. Don’t know if BR got rated as well.
