Human brains are the same or worse (smaller) for 100_000 years or more. What do you think is easier to read: one long line or the same text in columns with a suitable width? What do you think this width would be? The optimal width may depend on the language e.g., I'd use >1.5x for Java, to get the same information density per line as in Python. Your eyes/working memory don't scale with the width of your monitor.
