As the parent comment says, it's just another abstraction level. You have chosen a granularity, but even with "going to a website, enter your comment and click add comment" you are abstracting a lot. You are nto caring about connecting to a server, authentication, etc. The final user doesn't care about that at all, it's just telling the software to post a comment.
Right now the granularity may be "Comment on Hacker News article about UI this and this and that...", and in 100 years someone will say "But that's too complicated. You need to tell the IA which article to comment and what, while my new IA just guess it from reading my mind..."
I guess you could also argue that telling another person 17 tasks to do is just another abstraction level. That doesn't change that it's a completely different interaction paradigm than the ones before.
