Oh, these arguments make my head hurt:
>"The same 100 hour project with all the filler code obfuscated by Django or Ruby On Rails now takes 20 hours."
Ruby is so awesome that it simply saves 80% of your time? Really? You can't be serious. Yes, I understand the argument: If you remove all the fluff, you end up with the core problem, but I just can't believe that it's true.
>"Saving $800 over a higher skilled, more reliable, and more creative $80 an hour developer.[...] Its not worth $800, be happy with the $6,200 saved."
You should at least compare the 800$ to the 1600$, which is a saving of 50% - the risk might be higher, but the core problem is also in the "regular" project and you had no problem sourcing that out.
Seriously, these made up numbers are not helping. Maybe there is a truth to this argument, maybe not. But declaring you can get the same product for 20% of the price if you'd just use the right language is just wrong.
