This seems excessively handwringing about code rot. TIFF was introduced 35 years ago and still well supported. JPEG2000 didn't become super widespread, but is still used in many places. Smart passports encode your passport photo in JPEG2000 for example.

Another example is in radiology. Many thousands of medical images are created and stored in lossless JPEG2000 every day with entire ecosystems of software to store and move them.

Also in digital cinemas films are JPEG2000 sequences.

Exactly what they said. Movies in cinemas with digital projectors are distributed as sequences of JPEG 2000 images: https://en.wikipedia.org/wiki/Digital_Cinema_Package

The question isn’t whether any format from 35 years ago is still feasible to decode. The question is whether every format from back then is.
