No, you're still missing the point, but probably because the article wasn't clear. It's written from the perspective of a software startup who needs to get a concept out fast, and then iterate. If you're in a field where you do high volume trading, real-time data transmission or whatever then of course you should use something faster. I still assert that for the beginning startup, or anyone looking to build out an idea, they don't need to worry about whether Ruby is fast enough.
