I somehow agree with you @steemitblog that _steem will be the critical computational layer supporting all the different tokens._ but somehow your wordings are getting compromised on my side,  is it that _STEEM_ and _steem_ are two different things here?  I think that they were basically established to serve the unique functions for which they were introduced. 
**Pls can you clarify me on the difference between STEEM and steem and is each assigned a peculiar function to admit?**
