@BeAware it is a nice thing to do, that's true, but........let me give you an example situation.
Let's say, for instance, just for an example, that you took a screenshot. A screenshot of a browser that has a web page opened in it, which contains so many details. Many details.
And now, let's add to it that you're in hurry in your real, actual life. You, remembering the ALT text requirement, is finding out that it will take you hours to describe in detail your image.
And now let's add to this that you have several images, and each of them will take you HOURS to describe.
To me, it seems to be a waste of time to do this. Like honestly, I do add ALT text still, but only to my images that will not take HOURS to describe. But only so far often do I have cases when images will take HOURS to describe.
So yeah, it's a nice a thing to do, BUT IT ALSO REQUIRES YOUR SACRICIFATION OF TIME SOMETIMES, ESPECIALLY WHEN YOU HAVE MORE IMPORTANT STUFF TO DO.
And, personally - you may think whatever you want - I don't add ALT text to ALL my newly uploaded time anymore, except for easy-to-describe images.
How would you describe these images I shared on my recent post?

I, as far as I remember, didn't provided any ALT text for these images.
