College experience - Part 1: The (un)importance of lectures

It's been a few years now since I graduated from high school and there is one thing I surely don't miss and that is obligatory attendance at lectures. Yes, we have some kind of lectures like practice in the lab or presentation of our own program code which are required, but in fact we do not need to attend  lectures if we don't want to. It should be emphasized that I attend Faculty of electrical engineering and computing which is quite different from non-technical universities.

However, most of the non-technical and even some technical univeristies still have some kind of penalty if you miss the lecture. I can undestrand that is obligatory to attend speaking exercises and such, but apart from that, what is the point of forcing students to be in the class if they don't want to, if they are bored and don't learn anything from just sitting there, if they think they already know that subject, if the professor is bad in the transfer of knowledge and so on and so on? Who benefits from that ?
I just don't get it. At the age of 20 you are a grown person and if you think you can benefit from going to lectures- go to lectures, If you know you better learn at home by yourself- don't go to lectures and spend that time on something else.
For example, we are not obligated to go to lectures so I had to decide and found out from which lectures I would benefit and which of them are just waste of my time. It's very nice feeling when you can decide for yourself at 7 a.m. whether you will go to college or stay in bed and get some sleep so you can have energy later in the day for some quality study, or for doing nothing- why not?

In conclusion, we should all ask ourselves whether or not the person at the front of the lecture is adding anything of value to the raw information being presented.  If not, we should spend our time teaching and learning properly.

I really want to hear your opinion on this one. Especially from teachers, professors, students and of course from all of you who disagree with me!
Thank you for reading :)
