even if; although something ~
This pattern expresses that even when a certain point or situation is reached, the expected result does not occur or the situation remains unchanged.
に至っても is a formal, written expression that emphasizes that even after reaching an extreme or significant stage, something still does not happen or the state persists. It often appears in news reports, essays, or official statements. The focus is on the contrast between the advanced point and the unchanged outcome. For example, after many discussions or even after a serious crisis, the problem remains unsolved. In conversation, it sounds stiff; instead, people might say ~ても or ~のに.
