Why - 
summary notes that came out from yesterday's 2 why groups
- turing completeness
	one language is a good as another
	need to make the case the experience with two+ languages is important
	point out the contradiction - learning a new lang is easy; teaching them can't even fit in the curriculum
	domain underneath changes
	
	section of the report
		material in two sets of notes from yesterday


	students will only use one, preparing a student for this rare event is a waste of time
		- recent evidence that there are more and more languages, integrate other 
		- well maybe the 90s was an anomoly, very disruptive technologies (web), rare
			that such technologies will occur
			- last time: early 70s, pcs
			- in globalization, you won't get far thinking locally
		- we need hard data
			how many people use one languaage or one+
			- hard data in this are will be unconvincing to some
			- how many use only one language
				- how many of these work in a group where others use other languages
				- which language
			- which languages
		- another argument - breadth of knowledge in wildly different ways, using wildly different
			models, makes you a better more employable person
		- life long learning and employment longevity, choice in employment in the long term

		- at sun - most use more than one language, jvm/C/C++
		- modern web services
		- IBM plx, pl1, egl, cobol, C++, Java
			language you learned in school is not the one you use in industry
			- even stronger -- most people today in this industry -- do not stay the same, if you
			are good at changing languages, you will have more choice to change later

		- people who know that stuff (Jim's slides), 
		url, how many languages, from Stuart
		
		- intellectual horizon expansion

		- how to word this -- as objections?  articulate the positive only
			- don't want google to hit on these
			- when the course is optional, few students take the course
					this needs to be added and refuted

		- I never took the course and I don't need it
		- I took the course and never used it

		- Martin: I cannot identify a pl course that is required, I can't identify a pl course at all
			david gifford - no it was a grad class
			are our graduates defficient?  debated.
