Will internet and modern technologies replace a written word as a main source of information?

Have you ever heard that e-books and internet will replace the written word as the main souce of information? Of course, you have. To my mind this has almost happened.
To begin with, electronic readers have gradually become more and more convenient for users. Comparative consideration of electronics shows that over last decades these devices have become so powerful and their appearance so magnificent that they could be regarded as an excellent equivalent to books.
Secondly, these technologies save our forests which are known to be the lungs of the Earth. Increasing of survival rate of trees is a very important point/issue since humanity faces strong environmental problems. In my opinion, the greatest advantage of the internet and computers is the possibility to store an entire library in a single device no bigger than a common book. Just imagine it! Using only one device we are able to save a forest! What is more, many magazines (have) stopped printing paper issues and turned to on-line publications in order to reduce material losses and maximise profits.
In spite of all of the facts listed above, there are some disadvantages to internet reading. First of all, monitors cause substantial damage to eyes. Besides this, high-tech gears are much less reliable than non-electric mechanisms or things (methods? items?) and consequently, paper-based notebooks and books will serve (continue to be used?) for reading and writing in places such as pilots' cabins in planes, spaceships, scientific laboratories and so on.
To sum up, the written word will never disappear but modern technologies have made remarkable progress, turning books into highly specialized tools.

Thank you for kind attention! I would greatly appreciate it if you could estimate my IELTS mark for such essay.

I could not estimate your mark I'm afraid but it is an interesting topic and you have some good ideas. Good luck!

Presentation part1

Ladies and gentlemen, welcome to my presentation.
My name is Arn Walden
The topic of my presentation today is «digital art».
The reason that this topic is useful for you is How to bring a message in a creation»
We are going to talk about art.
These are, firstly, the context.
Secondly, the composition.
Finally we’re/I am going to speak/talk about colors and light
Due to the limited amount of time I have today, just seven minutes,
I’d appreciate it if you would keep your questions until the end. Thank you.

'These are' does not make sense because you have not said what 'these' are.

If this is oral, this is a fine presentation. If you are going to give it to somebody in written form. I would recommend 'do not' and 'I would' instead of 'don't' and 'I'd'.

Diary 1 Mar.

I have two new roommates who are both 23 years old. They are very young for me (They are much younger than me?).
One of them is from Mexico, the other is from Spain.
They were meant to come here on Sunday but the Spanish girl didn't come/arrive and we were waiting for her until 1 am.
It turns out that the staff who picked her up drove her to wrong host family. Finally she arrived this evening.
The Spanish girl lives in the same room as me. She gave me the impression of being kind of like a little boy.
I have to get used to living with her.
