Tools are just tools. Imagine scoffing at someone using a hammer, when in your less experienced opinion, they should be using NewHammer3.1.
Tools are means to an end. I much prefer working with people who care about the product and the business than what tools they used to build said product/business. I'm looking for "hey, you could save a lot of time by using tool Y", rather than "You people are idiots for even considering tool Z".
No. I can certainly imagine anyone scoffing at someone using a hammer when they are trying to dig a hole in the ground screaming "Tools are just tools!"
So yes, writing a website with assembler raises eyebrows and it is quite OK to ridicule bad languages such as PHP.
Why on earth would that be a problem? Why are you sensitive about tools? Do the tools have feelings?
