Re: Maple Vs Mathematica debugging / cost to write a system

2 million lines of C++, hm.  I guess that would translate into
200,000 lines of Lisp.

take 150,000 lines of public domain code from the DOE Maxima system.

Don't use "average" programmers.

Suddenly it becomes much easier.

Note that the vast majority of people working for
software companies are not programmers. The programmers
are not even especially highly paid, compared to
marketing or sales people. I think WRI has far more
graphics designers than programmers.

Making schoonschip can be expensive.  Take a commercial-product

million.
Need to sell 4 million copies at $1500 each to recover the cost.


Didn't you mean 5000 lines per year?
That would divide the programming cost by 10. A commercial
project requires much more than just programmers, so maybe
500 millions $ for such a project is a correct estimation.
