Blockchain technology never stopped continuing to improve. Same with VR/AR, the hardware keeps getting more comfortable and more capable. Package delivery drones have yet to be deployed at a large scale but are gradually increasing usage.
Arguably there have been many successful metaverses including things like Second Life, World of Warcraft, Minecraft and Roblox. The VR part of metaverse hasn't taken off yet due to comfort, expense and poor mixed reality capabilities. And we are still waiting for large scale open metaverses not controlled by a company. That probably will come eventually once we get better hardware and wider adoption more people understand the concept of the metaverse.
