What has replaced fuses?

I'm curious to know, what modern alternatives have emerged to replace the traditional use of fuses in electrical systems? Have advancements in technology led to the development of safer, more efficient methods for circuit protection? Are there specific types of devices or systems that have become the norm in today's world, and if so, what are they? I'm interested in understanding the evolution of electrical safety measures and how they've adapted to meet the demands of modern society.
