Must take issue with one point - whatever technical debt they may have amassed has little to do, I suspect, with holding on to the same boring old programming languages too long.

The shareholders should fire Brin if he suggests re-writing boring old "legacy" code in a sexy new language!

Haha, I certainly didn't mean to imply any of Google's current stuff should be rewritten. It's all very high quality, performant. Rather, I was thinking of new projects that might benefit from other languages or platforms.
