Re: second life vibes
Almost right, Second Life did add support for the Oculus Rift, it never had support for VR before that.
It was support for the Rift they gave up on although a third party viewer at the time already had rudimentary VR support and there is a project that still exists today, FirestormVR that lets you enable virtual reality for headsets such as the Rift, Vive and Quest
Linden Lab created a new World called Sansar which was intended to be their new VR experience and based on entirely new code. It actually does look amazing but never really took off and was later told to another company. The Second Life platform has actually been sold to another company now although while it remains profitable it will stay open.
