You have to read the entire sentence:

"""""""""Perhaps the reason nobody wants to touch the job is because they realize that computationally it is not practical, and there are already well established alternative procedures that will provide an acceptable result.""""""""""""


And then:

""""""""""Its ludicrous for a machine shop to say it cannot be done now.""""""""""

Remember to note the difference between "can not" and "will not"....
