The worst you can do is complain about it. Complaints lead to bitterness,
which in turn leads to your motivation being shattered.

This would be difficult because "content" can be a variety of different
things. In photography it can be a tree, a bicycle. In biology it can be
chromosomes or fingerprints. You would often end up with ad-hoc solutions.

I personally like the AI/machine learning approach whereby you feed (train)
a classifier and then assign labels to objects. Someone is already
exploiting 'free labour' for training purposes:

I am afraid that my main field of exploration is registration and models.
Segmentation is something I know from afar.

The best of knowledge often lies in the literature. Quite frankly, however,
I don't believe much in books as they are old-stylish. While they are
rather reliable, they are too sequential, and flat. Ask yourself a question
and then do a Web search to find an answer which you can merely trust. This
works well for me. Remember to quickly hop between citations (links) where
appropriate and form your own hypotheses.
