Google streets using this gonna be lit

That... is an excellent observation.

They're already there, although it's probably too computationally costly to do at scale.

I don't understand what exactly I'm looking at, since it's not my area. What is going on here?

Neural radiance fields (NeRFs) is a technique to create models of complex 3d geometry from a set of photo/camera pose pairs. The way it usually works is that the 3d geometry you're interested in (a car, a tree, etc.) exists within a static, bounded space (e.g. a unit cube). This research changes that requirement, allowing you to create larger spaces without the memory and computational drawbacks of "just making the bounded space bigger."

This seems like it could have exciting implications for VR.

Even after many years, one of my favourite things to do in VR is Google Earth. Yet, as a developer, it's a frustratingly closed platform.

I understand that they don't want me to put steampunk zeppelins into the world, but I so very want that.

What vr platform supports it?

I’d love to have some kind of remote robot that live streams to me as it goes around somewhere remote. Yes this has many obvious problems, but to be able to be in Tokyo for a few hours, hear the environment and direct what I want to see would be incredibly exciting to me.

I primarily work in Unity, but I'm not sure if that answers your question?

How has this not yet been deployed by a startup to unseat three-quarter billion market cap Matterport?

Luma Labs seems to be doing very well, they just raised some big funding

And Matterport will never see them coming, as their employees are banned from using Luma:

Competitors: No employee, independent contractor, agent, or affiliate of any competing 3-D capture company is permitted to view, access, or use any portion of the Service without express written permission from Luma AI. By viewing, using, or accessing the Service, you represent and warrant that you are not a competitor of Luma AI or any of its affiliates, or acting on behalf of a competitor of Luma AI in using or accessing the Service.

(Disclaimer: another banned competitor)

Is this even legal?

IANAL but I assume so. "Employee of a competing company" (whatever that means) isn't a protected class.

IANAL, but this seems easily circumvented by setting up an independent entity. (It's not an affiliate if it's not owned by the competitor.)

What a time to be alive!
