I'm having some troubles with the usage of will and going to in the future tense. I have searched this problem all over Google, but I can't seem to find the universal explanation (for example, one site says things 1 and 2, another site says things 2, 3 and 4, the third site says only things 2 and 3 etc.). I will be very grateful if somebody answers my question briefly and clearly, like this:
WILL Usage 1 - Usage 2 - Usage 3 - ... Example 1 - Example 2 - Example 3 - ...
GOING TO Usage 1 - Usage 2 - Usage 3 - ... Example 1 - Example 2 - Example 3 - ...
Also, have a look at the following sentence
Newspapers probably won't be used in the future because the Internet is slowly taking over.
Newspapers probably aren't going to be used in the future because the Internet is slowly taking over
I feel like it should be ''won't be used''. I'm having doubts because it has ''probably'' (which they taught us indicates a prediction so we should use ''will'') and ''because the Internet is slowly taking over'' (which they taught us indicates connection to the future, clear evidence by which we can judge and use ''going to''). I hope I'm not asking for too much. Thank you in advance.
