I've have finished high school since a long time. I don't write stuff to get "upvotes".
>"Here's a pro tip from a seasoned veteran of web development: if you want to do something really remarkable on a computer, you don't write it in HTML. You write it in C."
Gee, perhaps I've adreesed that, maybe in the part were I write specifically: "The peripheral details to his post [like] if he has a line about coding important apps in C and you disagree, don't matter".
Not only it doesn't matter (in the context of his actual message, with is about another thing altogether), but I agree with him.
95% of the important stuff we use to get amazing stuff done is written in C/C++. From our OSs and Word Processors, to Photoshop and our Browser. Heck, even Google Search is done in C++, and even Facebook had to create a C++ PHP VM to handle the amazing volume of data they do.
Seen any web stuff that's much more than "let's recreate stuff we had on desktop (See: Atwood's Law) with easier deployment but crappier performance and usability"?
And, more importantly, that doesn't depend of a huge stack of C/C++ code underneath? (From the JS JIT to the browser, to WebGL, to the OS down to the TCP/IP Stack).
