There exist plenty of reasons to colorize grayscale photos in 2026.

* a huge corpus of historical imagery

* cheaper grayscale cameras + post processing will surely enable all sorts of uses we haven't imagined yet.

* a lower power CCD and post-processing after the fact or on a different device allows for better power budget in cheap drones (etc).

* these algorithms can likely be tuned or used as a stepping stone for ones that convert non-visible wavelengths into color images.

And that's just off the top of my head as someone who doesn't really work with that stuff. I'm sure there are plenty of other reasons I can't think of.

Grayscale cameras are not that much cheaper than color cameras. And if you decided to use a grayscale camera on purpose, you probably do not care about the color information (which would be totally "made up" by the colorizing algorithm).

Also, if there are only grayscale photos of you, you were probably born before 1900, and all your friends or your children (who might want to colorize your photo) are probably dead, too.
