China has launched the first 12 satellites of a planned 2,800-satellite space-based distributed supercomputer - but do the plans behind it make any sense?

The constellation's total processing power will reach 1,000 POPS (1 exaFLOPS), rivaling today's top supercomputers. However, its 100 Gbps laser links and 30 TB per-satellite storage are more limited than ground-based systems' high-speed interconnects and larger capacities.

*"The satellites also have the capability to create 3D digital twin data that can be used for purposes like emergency response, gaming, and tourism, ADA Space says in its announcement."*

OK, but why go to all the trouble of 200+ rocket launches to put something in space you could build better on the ground?

I can finally practice bass in mixed reality. Modifying exercises to my level makes it more fun and easier to get my daily 20 minutes.

The falling cost of solar panels and batteries means the US could now meet 80% of its electricity needs from just solar power alone, for the same price it pays for gas-turbine-generated electricity.

For electricity grids, solar gets more expensive the more of it you use. The higher the percentage of solar in the mix, the more you need to over-build and use batteries to account for the least sunny parts of the year - January in the Northern Hemisphere.

But rapidly declining prices for batteries and solar panels are changing that. If built, at the lowest prices currently available in China, the US could now supply 80% of its electricity from solar+batteries cost-competitively with gas.

If prices continue to fall, using existing gas turbines as backup, the day is coming when the US may be able to supply 90-95% of electricity needs from just solar.

The political winds may be against this at the moment, but the economic truths will win out in the end.

Are there good-paying AR/VR jobs in India or remote?

Hey everyone,

I’ve been exploring the AR/VR space lately and I’m seriously considering shifting my career in that direction. I’m particularly interested in development roles (Unity/Unreal, C#/C++, XR SDKs), and I’ve noticed there’s a lot of global hype around immersive tech but I’m trying to figure out what the real job market looks like in India (or remote for Indian devs).

Some questions I have:

Are there well-paying AR/VR jobs in India right now, or is it still a niche?

What’s the salary range like for mid-level or senior devs in this field?

Are Indian companies hiring actively, or is most of the work for international startups/firms?

Any tips on how to break into the field or where to look for opportunities?


I already have a background in general software development, and I’ve been upskilling with Unity and AR Foundation, but would love to hear from folks actually working in the industry.

Any insight would be super helpful!

Thanks in advance 🙏
