The day I started work at NRC I was told of our efforts to summarize documents using artificial intelligence. NRC has moved on to other things but document summarization has remained the subject of sustained research elsewhere ever since. Even humans have difficulty summarizing documents (so my years of teaching critical thinking can attest) and so it's not surprising machines struggle as well. But progress is being made, and yes, I would trust a machine to summarize documents for me (especially if I don't have legions of humans to do the work for me).
