could the words "they're" here be replaced by "it's"?
-If you don't want to get teased about that,get a doctorate.
-I have one, they're great.

why here is "they're" but not "it's"?
Thank you.

Question

could the words "they're" here be replaced by "it's"? 
-If you don't want to get teased about that,get a doctorate.
-I have one, they're great.

why here is "they're" but not "it's"?
Thank you.

Answer

The meaning changes slightly.
I have one and they're great. = I have one and they are all great.
I have one and it's great = I have one.  The one that I have is great.
[Note that 'and' should replace the comma for better form]

Answer

In your example, I agree it should be it's [ it is] because it is referring back to the doctorate.
