That real estate in the brain will be taken over by neurons that control sense of touch and a sense of hearing, and your, indeed, hearing and touch are much better, higher acuity, and faster in blind people.
The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.

Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

Would love a "what would change this verdict" RSS feed. Sign me up if it exists.
And you can demonstrate that people who are born blind are better at hearing and and at touch and so on. They can discriminate things much more finely.
So it turns out um you know right people who are born blind what we call the visual cortex at the back of the back of the head here that gets taken over. It's no longer visual. It becomes devoted to hearing to touch to memory things like this.
