I would argue this take conflates attention with cognitive overhead required because of a lack of training. Navigating with our closed feels like it takes more attention because we’ve practiced so many hours navigating by sight that it no longer feels cognitively burdensome. A bat would have no trouble navigating without sight for the same reason. I don’t think most people would say giving up our sight for echolocation would reduce our attention, it just transforms it.
