There are practical reasons to learn it, if you do radio operations. A morse signal doesn't require the same bandwidth that a voice signal requires, so you're able to focus the power of the transmitter into a tighter bandwidth, and broadcast with more power than a voice signal. In addition, you can understand the information in a morse signal in the presence of much more interference than you can understand a voice signal. So it's actually quite practical when doing radio operations to use morse, even today.
