Machines cannot blog in the same way or level that humans do. Would a machine think to post this particular post? Unlikely, machines cannot dip into imagination and thought and think of topics that are completely unique, they can assimilate in the same way we do from our previous knowledge bank of words, quotes, literature, encyclopedias and lyrics.

But the truth is success in monetary value has little to do with the content and more to do with how and to who the content is delivered and consumed by, so maybe machines will be able to blog more successfully based on how intelligently they are programmed...

But when it comes to the possibility of quality content that draws from memories and experience Humans still reign supreme imo.
