What is the point of HiFi?

I'm curious, what's the real purpose behind HiFi technology? Is it just about the crispest audio quality, or is there a deeper meaning to it? With so many options for listening to music, why would someone choose to invest in a high-fidelity system? Is it a matter of personal preference, or does HiFi offer something unique that can't be replicated by other audio formats? I'd love to hear your thoughts on the significance of HiFi and why it matters in today's world of digital audio.
