To give a perspective. Former Second Life founder and CEO founded Highfidelity.com to create an open source social VR world platform. 5 years later, and with at least 75M dollars in funding the platform is empty[1], even though it is in Steam, and even hardcore VR creators dont seem eager to use it. They had to pay users to join them for their stress tests. The creators' stories in the forum may be telling about the shortcomings of creating amd using VR regularly[2].

Meanwhile, secondlife's open source clone, opensimulator, has thousands of regions and users online[3] despite being a super buggy platform, with less than $0 in funding.
