One of the first things I learned when I started fixing / building things was, use the right tool for the job. Every job is different and requires different tools. Your "friend" is obviously closed minded, but don't discount the idea that his tools might actually be the right answer for this particular problem. Learn from his strengths. Live with his weaknesses and combine it all to be a better, more valuable asset yourself. Don't close yourself off to other ideas. Managers appreciate employees who can offer multiple solutions for them to choose from. Linux offers very low cost solutions with open source transparency. Windows / Visual Studio is an excellent RAD platform but comes at a cost. Return on investment is key in the "real world".

Try MSI, theirs works really well.

The UN does have an agreement that no country may claim extra-terrestrial property as their own or as a colony. When people start living there however, they will start to claim property as their own. What are people on Earth going to do? Kick them off? If they try, it will just be the start of the first inter-solar system war. Viva los lunar revolutionaries!
