The Smartest Companies are in the Same Room, but are not Building New Products Together...for you
A brief follow up to my previous post, "The State of Stateless Linux (And the Future of Solar Computing)" is about the technology industry as a whole.
Obviously, money drives product development - anticipated revenue streams from new products. But sometimes newer is just cheaper materials, rather than a new feature, which of course, isn't always a bad thing, since the savings can be passed down to the consumer.
In the Qualcomm case, The UNO Q isn't really innovative in terms of features. It might be a cash cow if Raspberry Pi wants to get out of the consumer division and only focus on corporate/industry customers. That too, isn't always a bad thing- serving consumers where a former company is unable or less willing. After all, Qualcomm has a large patent portfolio, and wouldn't need to outsource every thing or anything. This is the same Qualcomm that wanted to make a bid on Intel to buy them out, however Intel & The U.S had "other plans."
Now, sometimes it might be a good idea to choose your battles wisely. For example, Qualcomm is known more for its mobile chipsets and wireless IP, rather than single board computers. So them amassing a war chest was probably prudent if they decided against that 10 years ago. And of course there are also potential benefits to avoiding tariffs since it is an American company, whereas the UK, however unlikely it would face tariffs to the extent of other countries, could see a surcharge on even a $35 Raspberry Pi.
Even so, product development often follows other successful products, and sometimes it is simpler/easier to develop a cheaper product that does the same thing at the same energy consumption for a lower cost, than something that uses significantly less power for the same price- because energy is still cheap, especially at the low end where devices consume just a couple watts of power.
There are certainly countless instances where companies work together to build a product- an EUV machine isn't built by one company, for example, but uses a laser from Germany and materials from the U.S. and Asia:

The State of Stateless Linux OSes, and the future of Solar Computing
The title is more of a gag on the other parodied State of the Union addresses, like State of the Onion by Perl Developer Larry Wall: https://www.perl.com/pub/2006/09/21/onion.html/
Stateless applications, or even machines, may involve some amount of storage, even if it is not local. The purpose of stateless systems may have diverged with increasing options/capabilities, but its adoption in embedded systems can still have a lot of utility.
https://www.redhat.com/en/topics/cloud-native-apps/stateful-vs-stateless
A stateless application may comprise only one part of a lightweight system, whereas the rest of the kernel and OS might have stateful applications.
What about Stateless OSes?
Depending on the need, such as a LiveCD/USB, a stateless OS isn't going to save info on ROM, but it can serve a useful purpose such as on PuppyLinux, which boots into RAM and allows a persistant storage option. One theory is that developing a new, lightweight system might be easier to select off-the-shelf stateless applications/modules, and interfaces, then integrate them into a single OS that limits where storage must take place.
Rather than starting from scratch, like Gentoo (which itself isn't technically from scratch), building an OS with predefined and pretested benchmarked applications can produce a list of memory requirements, and then the applications can be loaded as separate, single application OSes. This might allow bypassing higher memory needs, at the expense of a "truly" userspace OS.
Stateful Userspace, just not all at once
Another Four Core A53... in 2025?
What I think is needed

Why 16-128MB? Because the era of Solar is upon us.
| Remember when these could run on their own? (Some had a backup battery, but still) |
Low Power Memory makers typically sell just a few MB, at most: . https://www.sure-core.com/memory-products/ (SRAM), https://www.crossbar-inc.com/, https://www.weebit-nano.com/ (ReRAM) I am not really sure which memory suppliers are developing for the high end (many MB), but I imagine if it's really leading edge, their partners aren't publically advertising it, esp if they are using it internally to confer or research some further competitive advantage)
