I am am almost 75 years old and some kind of excited about this new 
industrial revolution that is creeping up on us all.
    My grandson is programing cnc for several different companies 
running cnc at home building products and to a lesser degree 
subcontracting. These little home shops don't have to pay employee 
healthcare nor pay corporate taxes.  They can likely pay the lower  
capital gains taxes on what their robots, cnc mills and Fab machines build.
    When I think that I can download and install Ubuntu and EMC 2  buy a 
driver box from a shop that may have built it at home and even go so far 
as to build my own mill from parts that may have been built in a home 
workshop it's exciting.  Some guy in his back yard may well cast the 
parts in his back yard for me out of scrap metals.   "WOW"   This not a 
little thing it can be huge. 
    It may well change government or it's tax methods.  It may turn out 
that we will do away with income tax and have to tax these products when 
sold in the form of sales tax.
    These same people will not have to drive 20 miles to work everyday 
and may not wear out a car every ten years making that trip.  Mass 
transit may be an idea that has come and is now going.
     I have been dreaming about this stuff since  back in the late 
1960's when I first began to use NC and then CNC. 
    I think the Chinese have done us a huge favor by taking 
manufacturing  away to free up the young, smart as can be young 
entrepreneur that are beginning this new economy.
    A lot of this, I think is inspired by the writing of free software 
like linux.  Then from there moving on to free programs like Cinelerra 
and emc 2.   I really believe free Linux has reached a kind of critical 
mass that is now allowing it to move into programs that can do physical 
work and manufacturing.
    I am presently repairing microscopes but will soon be making medical 
parts for hospital beds, Xray machines etc.  These will go freely all 
over the world where they are sorely needed and a big part of this will 
be, because of EMC 2. I could not make enough of these without cnc.
    I will need to make some parts to sell as well.  I can't run a 
backyard shop without some income from someplace so I will make and sell 
some parts for this purpose.  I have also decided that some of this 
money needs to go to the writing of software like Emc 2 so I plan to 
donate some of what I make to help develop. It won't be much money but 
it will help. I have never done this before because I only used free 
software in playing with my computer  but now this same software is 
doing my work for me so it only seems fair to return something.
    Wouldn't it be something if free software changed the economy of the 
whole world??  I find this really exciting stuff and it seems it may go 
as far as you can imagine.
