Yes, many completely ordinary cars today can match or out-accelerate a lot of the older cars mentioned in the article but that is only a single measure. If you're a "car person," you owe it to yourself to spend some time driving a 911 so that you can truly map that image to a physical experience.
That said for the 911, each of the cars that enthusiasts tend to love has its own character. You can give them all very similar performance specs on paper and driving something American, Italian, or German will still be a completely different experience; overall, the fastest car will not necessarily even feel the fastest; the slowest car that you can consistently drive the hardest might prove to be the most fun to drive.
