A very key problem is the common narrative that green policies and the EU allegedly caused the downfall of the car industry (-> "Verbrennerverbot").

In reality, a way bigger impact seems to be that the Chinese govt stopped buying German cars once they could build their own (which they have been always transparent about).

Unfortunately, this misdiagnosis leads to the wrong conclusion to double-down on a obsolete business model of the car industry, instead of diversifying away from it.

I think that is a fantastic insight that 'Making niche solutions is the point' with 3D printing.

Unfortunately, it is still very hard to _design_ niche solutions. The usability of CAD tools did not really improve at all in the last 20 years..

A big advantage of this technique is that the assembled model is 'isotropic'. If it was printed in one piece, it would be easy to split along the layer lines.

But when printing the plates separately, every face is equally strong.

Great project!

really nice to see well designed, useful 3D printable products.

These kind of designs are essential for 3D printing to graduate from printing baby yodas only. Also, the high-quality photography and documentation helps a lot to go for the 3D print over temu.

> The Apple Vision Pro is the Northstar the VR industry needed, whether we admit it or not

I think that sums it up pretty well. More companies should launch products like that!

There is a cool study that says that the likelihood of your startup suceeding does not peak until your late 50s.

I think the public debate is so skewed towards young founders because it is so centered around extreme outlier founders and companies.

Since self-driving trucks do not need to rest, they can be also a lot slower while on the road to help with safety.

I'm wondering why there is so little talk about changing road infrastructure to make self-driving easier to pull off.

E.g. dedicated lanes for self driving or hand-off stations where human drivers can take over etc etc.

Amid the massive potential upsides, any reasonable government would invest in measures that turn out to effectivley improve self-drivability of the respective national grid.

15% of Model 3's fail the mandatory audit after 2 years due to 'considerable defects'.

There is?

What I can verify:

To the best of my knowledge, this is the first work that proposes putting a photorealistic, perspective corrected face on a VR headset.

"FrontFace" (https://dl.acm.org/doi/10.1145/3098279.3098548) is the first work that proposes putting eyes on a display on VR to "lower the communication barrier".

Facebooks paper on their technology is quite amazing: https://dl.acm.org/doi/10.1145/3450550.3465338

I'm guessing (?) Apple's approach is similar.

no insider knowledge, I just know that the work from facebook cited our work: https://research.facebook.com/blog/2021/08/display-systems-r...

They also add the display that would work with different angles. So it looks like, maybe Apple implemented Meta's research. The timeline could work.

For completeness, there is also another paper "FrontFace" proposing a similar idea that was published around the same time: https://dl.acm.org/doi/10.1145/3098279.3098548

Adding multiple viewpoints is actually sth Meta first proposed, based on the paper from above:
