At 27, I still feel old in the same regard as a lot of the ways the author is talking about. A lot of things I'm seeing reeks of being a fad. I'd rather avoid naming any technology or framework, but my instinct has been to avoid planting my seeds in soil that's churned up every 6 months and keep an eye toward that which has been solid for a decade and is likely to continue. I don't mind learning a new language -- there are a couple I'm hopeful toward and think could be long-term winners. But I'm not about to waste grey matter on things I suspect will be obsolete before I can even reach mastery.
