1. Improving the colourisation algorithms has value, it might be that the available colourised photos of celebrities have inaccurate colours or are of poorer quality than say, one done with a diffusion model that can be instructed about the colours of certain objects

2. Don’t forget about B&W films! Getting automatic methods to be consistent over a long length is still not 100% solved. People are very interested in seeing films from WW1 and WW2 in colour, for instance.

3. Plenty of people (myself included) have relatives in their 80s or 90s. Or maybe someone wants to see their ancestors from the 19th century in colour for whatever reason?
