Why is neon not popular anymore?

So, let me ask you, what's the story behind neon's fall from grace? I mean, it was once all the rage, lighting up cities and capturing imaginations. But now, it seems to have faded into the background. Is it a case of better, more efficient technologies taking over? Or is there some other reason why neon is no longer the go-to choice for that iconic, vibrant glow? I'm eager to understand what's behind this shift and what it says about the evolution of lighting technology and consumer preferences.
