Communication:

VR is the most human and freeing way to hang out digitally. Unlike videocalls you get the feeling of being face to face with someone, it's less fatiguing, it's more natural, you can make eye contact, it actually provides missing subtle body language through parallax depth cues, there are far more interaction capabilities, and you get to share spaces and activities with people rather than stare at each other's backgrounds on a video call.

Telepresence:

Live digital events like concerts and sporting events never feel like you are there with the artists or there courtside if using a TV/Phone etc. It does with VR which fills the need for people to want to be there when they can't go IRL.

Education:

VR education is a great way to further engage students and have them learn in a more hands-on approach/visual approach to get them to retain information more easily. Concepts can be explored in new ways such as going inside blood cells, touring the solar system at real scale, or manipulating dangerous chemicals that wouldn't be allowed in a real school lab.

Training:

Training people in VR is a great way to put people into dangerous scenarios or build hands-on knowledge of concepts that would otherwise require unfeasible amounts of resources. Having a medical student train in VR in their dorm room would be a new benefit beyond just reading in their dorm.

Fitness:

Giving people a gamified experience can help entice people to get their share of exercise with a side of fun. This tends to allow people to exercise for longer periods as the body just forgets, to some degree, that this is exercise because the user is enjoying themselves in game-like experiences with the immersion of VR. This can be done in a shared virtual environment to help encourage your fitness routines and have personal trainers that can guide you better than on a videocall.

Health:

VR is a way to treat and/or solve various medical problems mostly in the area of neurology due to how VR can easily kick in neuroplasticity to help rewire our brain and restore functions or improve conditions. VR is known to treat amblyopia, strabismus, diplopia, nystagmus, stereoblindness, macular degeneration, achromatopsia, PTSD, various phobias, social anxiety, general anxiety, depression, chronic pain, stroke recovery, phantom limb pain. Some of these are for home users and others would be received in a professional environment.

Computing.:

Being able to have as many monitors around you as you want wherever you are without taking up physical space is a great way to enable workstation-grade productivity for frequent business travellers or those with small spaces.
