People are definitely depressed, especially relative to how things should be. You don't see it much on hacker news, but you do on other forums. 20 year olds who are relatively well educated who see no future.

I don't want to take anything away from you. If you are enjoying your job and your life, that is truly great. But I would encourage you to take care of your future. Make sure you have progression, or something else, to show for it. You wouldn't be the first one to change perspective when life, or work, changes.
