Josh Bersin published a new essay on February 17 with a single question at its center: what has actually changed about leadership? The post, "The World Is Accelerating: What Has Changed About Leadership?", runs on his long-form blog at joshbersin.com and opens with a sentence that frames the entire inquiry.

"It's a tumultuous time to be a leader," Bersin writes in the piece. He pins that turmoil to two specific forces: the acceleration of AI and the change in global politics. The post then widens the lens and turns to the question at its title.

What does the essay say has changed?

The post treats the leadership literature as both foundation and reference point for the new inquiry. Bersin notes he has worked through "hundreds of books on leadership" over his career, a body of work he treats as established canon. He invokes Peter Drucker's "The Effective Executive" as a foundational text among them, signaling that older writing still anchors his reading of the field.

That framing matters because any contemporary answer must weigh against decades of accumulated advice already on the shelf. Bersin's invocation of Drucker suggests he reads the current moment as a continuation of older debates rather than a clean rupture with them. The essay thus begins by reclaiming the canon before asking what must now be added to it.

Why does the question land now?

The post arrives against two pressures Bersin names in his opening paragraph. The acceleration of artificial intelligence and the change in global politics together form the backdrop for his question. Bersin frames those two forces as the reason a fresh look at leadership has become urgent, and he treats neither pressure as background noise.

Each force, in his framing, demands a response from leaders responsible for organizational direction. The question at the post's title sits between those two pressures and the leadership canon he has spent years reading. The framing is intentional: the new is set against the established.

What signals does the post send to HR leaders?

Bersin reaches for the canon before reaching for the new. His reference to Drucker, paired with his count of "hundreds of books," signals continuity rather than dismissal of established leadership thinking. The piece reads as an invitation to revisit foundational texts through the lens of AI acceleration and political change.

The essay also signals that Bersin considers the question unresolved. He poses it without closing it, leaving room for follow-up commentary on what leadership development must now look like. The post is a prompt dressed as analysis, and the framing invites response rather than agreement.

What should HR leaders take from the post?

The post functions less as an answer and more as an opening. HR leaders reading it should expect to revisit their own leadership frameworks against the two pressures Bersin has named for the field. The full essay runs on Bersin's blog at joshbersin.com. Readers should expect the analyst to return to the question in further commentary as the year unfolds, sharpening what leadership development must look like in the period ahead.
