Statements like "[A technology] scales" are senseless even on their face. Scaling is an architectural challenge. Language matters, but it isn't the only factor

Statements like "[A technology] scales" are senseless even on their face. Scaling is an architectural challenge. Language matters, but it isn't the only factor and most likely isn't the most significant one. Claiming Ruby doesn't scale is even more idiotic since there are plenty of sites running Rails that have proven they could scale and whose response times are a lot less than 3s. I realize those are obvious gripes, but since this is on the front page I assume people thought it was interesting or informative in some way and I'm interested to hear their arguments.
