you only need few thing to have a immersive experience in metaverse. first i would say a super light weight VR headset is a must. next to a photorealistic environment, which thanks to unreal engine 5 we are literally there! also the most important part in my opinion is Elon Musk's neuralink. being able to put your VR headset on, lay back on your couch and telepathically control your character's movement, is as immersive as you can get.

sadly we're probably 5-10 maybe 15 years away from a solid experience.
