God I fucking hate this comment. Yes the poster could have just googled it. But you know what? I had never thought about what’s in those towers. So I clicked on the topic to come to comments and learn something. Instead I find your snarky worthless comment that contributes even less than the OP. Asking questions on here is a way to share curiosity and foster discussion. And lemmy needs more content, not less. So I hope no one takes your comment to heart.
