Heat pumps and better insulation. It's magic how heat pumps pull heat out of thin air. I honestly think part of the reason they are not adopted as much is people can't understand them and don't trust them because of their ignorance. Insulation seems pretty boring until you start to realize how much energy can be saved by modern insulation.

Along the same line of thinking, tankless water heating [1] seems like a no-brainer. It surprises me that places like the US have not used it as the default from the start.

They are good. But not in very cold environments. I have one and when there is more than two degrees of frost it struggles. So for a lot of continental areas they are almost useless since they do not function when you really need them. For temperate climates and coastal regions they are wonderful.

I have one for my 20m2 shed, it works down to -5c at least.

Granted my shed has quite good insulation, but still.

Worst comes to the worse you could use a ground source heat pump.

Allergy immunotherapy. I started a company on the backs of this treatment. The way we treat allergies today, with Zyrtec and Claritin, is medieval medicine. It doesn't solve the underlying problem; it just tries to cover it up. Allergy immunotherapy is the future. Most people don't realize that allergies are now a curable disease. In the future, taking Claritin for allergies is going to seem like taking Tylenol for a…

Surprised to hear this is uncommon, I received allergy shots >20 years ago and it was the only allergy treatment (after many attempted medications) that had a sizable impact.

Besides the delivery vehicle, what are the differences between allergy shots and these droplets?

Developments in the AR/VR space. The haptics stuff coming out is really cool and may be consumer friendly in the near future. Meanwhile headset tech is seeing major investment and light field technology is going to do amazing things for this space.

The Oculus Quest 2 is so cheap for a very high quality and high resolution experience. And even more importantly, it’s extremely simple to setup.

Wireless VR really is a necessity for it to become more than just a tiny niche.

Not yet mainstream, but it’s actually a joy to use and I think we’ll have significant marginal improvements over time which will keep making it more and more worthwhile.

I think the real thing will be commercial applications of VR, where companies use it because it’s the best way to get certain kinds of work done. And NOT desk work, either. We’re maybe a decade or two from that being mainstream, but it’s going to be a significant improvement.

The GraphBLAS[1] is an amazing API and mathematical framework for building parallel graph algorithms using sparse matrix multiplication in the language of Linear Algebra. There are Python and and MATLAB bindings, in fact MATLAB 2021a now uses SuiteSparse:GraphBLAS for sparse matrix multiplication (A*B) built-in. [1] https://graphblas.github.io/

I am working on GraphBLAS-based implementations right now. While the API itself is great, using it full-time I notice documentation is still quite behind and still not too many features. Also there is almost no community outside academia. Crazy efficient though, and very solid overall

I've received allergy shots in the past. Seems to be a relatively common treatment in the south. It's just inconvenient due to office visits.

Looks like the innovation here is the move the serum from intradermal to a liquid, oral treatment?

That's a big leap for me. I spent 1 hour twice a week commuting to get allergy shots.

I'm not sure this is exactly under the radar but I'm excited about wearable AR. No it doesn't look real but once you get past that we have some amazing tech on the horizon. Microsoft and Oculus have hands free controls that actually work. Inside out tracking is progressing quickly. New UX patterns are getting forged. I'm exited to see what we'll have in a few years time. In my mind its far more exciting than somethin…

Inside out tracking is crazy good. I have a Quest 1, and this technology is seriously impressive. Quest 2 is significantly better and cheaper.
