ELI5: Why, although planes are highly technological, do their speakers and microphones "sound" like old intercoms?

EDIT: Okay, I didn't expect to find this post so popular this morning (CET). As a fan of these things, I'm excited to have so much to read about. THANK YOU!

I’m a commercial airline pilot and there is a lot of misinformation here. First of all, 99% of the time we’re on VHF AM, not HF AM radio like people have suggested. Second of all, the radio has nothing to to do with the intercom anyways. The real reason is weight. Good speakers are heavy and the fuel to carry those around for the life of the airplane costs thousands to millions.

TLDR; Good speakers are heavy and cost too much fuel to carry around.
