It's not misleading at all --hinging on a literal reading of that quote is just disingenuous. For the record, further down that blog post[1], Wolfram writes (emphasis added):

"So what does it all mean? I think it's pretty important, because it really changes the whole process --and economics-- of programming. I've even seen it quite dramatically within our own company. As the Wolfram Language and the Wolfram Programming Cloud have been coming together, there've been more and more places where we've been able to use them internally. And each time, it's been amazing to see programming tasks that used to take weeks or months suddenly get done in days or less."

How is that not a very concrete claim about the product?
