So far, all 2013 papers on hep-th and gr-qc in the arxiv were disappointing. No new ideas arose on the theory of everything. No new TOE proposals.
Some obstinate people still work on supersymmetry or strings, even though they do not lead to predictions or uniqueness. Some quantum gravity people still work on their pet models, but without any predictions or uniqueness.
There are no new opinion pieces either. In the past, people used to write texts in which they told what their opinion are. Nothing hard, just their own opinions and beliefs. All these are gone. Nobody has an opinion any more about where to look for unification. No opinion pieces means that nobody has the courage to tell others what to do, where to search, or what to speculate. A whole generation of leaders, professors, and researchers has become silent.
In the past years, every researcher used to give interviews. Nowadays, interviews only cover multiverses and similar nonsense. The search for a TOE has stopped to be a topic for interviews. Researchers have lost faith, it seems.
Look at Steve Carlip, well-known researcher in general relativity. Since 2009, he thinks that space is made of "fluctuating lines". He tells this in every paper since. What happened? He was called all sort of names by colleagues. And he has to focus on defending the approach, instead of building on it.
Yes, it is hard to speculate if others call you crazy. Yes, it is hard to brainstorm if others call you mad. Simply forget the criticisms! Please, dare to dream again! Dare to speculate! Dare to brainstorm! Find the nature of nature! Find the components of nature! Inspire the young women and men we need to find the TOE!
