in this day and age

In modern times

In this day and age emphasizes that something is true or surprising given current times: In this day and age, you'd think we'd have figured out how to prevent power outages.

The phrase often carries mild exasperation that old problems persist or old attitudes survive into the present.

It's slightly redundant—"nowadays" says the same thing in one word—but the extra weight serves rhetorical emphasis.
