This question asks how far artificial intelligence is taking over what people do, and whether it is replacing whole jobs or only the routine parts of them while leaving human judgement and responsibility.

The question treats a 'role' as a unit that can be wholly taken over, when most roles are bundles of tasks, and AI excels at some tasks while leaving the judgement, accountability and human contact that define the role.
domain: AI is replacing humans heavily in routine and predictive tasks, partially in skilled cognitive ones, and barely in roles defined by responsibility, care or moral judgement.
How to approach it. Calibrate how far AI is replacing human roles, distinguishing tasks from roles and capability from authority, since automating a task is not the same as replacing the human who is responsible.
Artificial intelligence is replacing human tasks rapidly and human roles only rarely, because most jobs are bundles in which AI absorbs the routine and predictable parts while the judgement, accountability and human relationship at the core remain stubbornly human, so the displacement is real but the wholesale replacement the question implies is not.
Capabilities once thought safely human, writing, diagnosis, creative drafting, have fallen quickly, so the comforting claim that judgement and creativity are reserved for people looks less secure each year, and an honest essay cannot bank on today's limits holding. This deserves real weight. But even rapid capability gains keep crashing into the same wall: a machine can do the task, yet someone must still want the outcome, authorise it and answer for it, and that someone has so far remained human, which is why roles erode at the edges while their accountable core persists.
Artificial intelligence is replacing human tasks extensively and accelerating, but it is replacing whole human roles only at the margins, because the parts of a role that involve responsibility, moral choice and human relationship have not transferred to the machine; the displacement is therefore large and disruptive without being the total replacement the question invites us to imagine.
The question treats replacement as something AI does to us, when whether humans are replaced is decided by human choices about deployment, regulation and value, so AI has no autonomous power to replace anyone; the real driver is the people and firms who choose to substitute it for cost, which makes this a question about us, not about the technology.
If a rival firm or country adopts AI and undercuts everyone else, the choice to keep humans becomes a choice to lose, so in practice market logic can make replacement feel as forced as any natural law, and pretending it is freely chosen can sound naive. This is a real constraint. But constraint is not inevitability: tax, regulation, labour standards and coordinated policy can change the incentives that make replacement rational, which is exactly what regulation and reskilling schemes attempt, so the pressure is powerful yet still, at bottom, a set of human-made conditions we can alter.
AI is not replacing the role of humans, humans are choosing to replace humans with AI, and the extent of it is set by decisions about cost, law, value and retraining rather than by any autonomous power of the technology; the honest answer to 'to what extent' is therefore 'to whatever extent we permit and design', which puts the question back where it belongs, with us.
Option A calibrates by conditions, distinguishing tasks AI replaces from roles it cannot because accountability and relationship stay human. Option B rejects the premise that AI is the agent at all, arguing replacement is a human choice driven by cost and constrained by law and values. Both are defensible: A is the disciplined task-versus-role 'to what extent' answer; B is the premise-rejecting move that relocates agency from the technology to society, which scores higher if the choice framing is sustained.
