My learning stages for language processing

It is so idiosyncratic (not counting my math background):
1. Did the automated reading project, the "note reader", for customer order notes. [C++]
2. Built a noise reader at home, re-implementing ideas from work. [C++ and Python]
3. Created narhwal - the long term project that should contain all. [Python]
4. Started designing the "naomi" chatbot to accomplish more than the note reader: have to have language responses; cannot bail with an "alarm" category...or much less often; have to know when enough has been said to proceed; have to alter responses on the way through; etc. [Python and maybe - with a colleague- Java Script.]

We'll see how it goes with my learning curve. At my age, all learning curves are races with senility.
