TML is the most ambitious project I know of. What I learned from a quote from Bruce Lee (I remember you appreciate martial arts), is that one of the keys to his success was to aim high.
The quote:
“Don't fear failure. — Not failure, but low aim, is the crime. In great attempts it is glorious even to fail.” - Bruce Lee
This holds very true. Whether we are talking about Facebook which had the extremely ambitious mission of making the world more connected, or Google to organize the world's information and make it useful, or Bitcoin to create peer to peer electronic cash. Tauchain and Tau has the kind of ambition where the reward for success of this project is a world changing impact.
TML being not just a language, but a meta language, allowing for advanced users to define and configure languages. This is something no other crypto project has even attempted.
