This concept raises more questions than the site answers:
* what's the point of landing in tow? The safety aspects and the failure modes are enormous
* it's unclear where the 65% fuel saving comes from. Riding the wingtip vortex on the inside produces downward momentum. In order to generate positive lift from the wingtip vortex, the follower has to be outside of it (e.g., gaggles of geese in wedge formation)
* taking advantage of wake flows, while possible (although 65% is highly improbable), would always be less efficient than optimizing a single airframe so that it minimizes the wake generation in the first place
* the site is missing footage of real flights. The 3 clips 10-seconds long are not showing what they claim to be showing. Also, does the "see flight tests" link work for anybody?

FYI the new Q has two 'high speed connectors' on the bottom side, for signals like CSI, HDMI, USB 3.1, etc.
Haven't seen any examples of bottom 'high speed' shields yet, though. They said there would be some made available.
Well, if all the interesting signals are on the mezzanine, what's the point of the Arduino form factor and pinout? Just to claim that they're supporting a widely used platform? Engineers can see through it.
The more I look at it, the more it sounds like a platform designed by M&A team

This reminds me of the Arduino Intel Galileo.
or Samsung Artik. Went nowhere in a hurry

This is desperation and I think it will go nowhere good.
Arduino has neither technical (standards, form-factor, pinouts), nor mindshare among developers that can be useful for high-speed, modern and upcoming AI-on-the-edge applications.
It sounds like Qualcomm is making a belated move towards robotics, but acquiring these assets is only going to distract them from becoming a successful player.

I think to Arduino, Uno just means 'Uno form factor, with shield pins in the same place'
Which is kind of sad, since the Uno pinout is horrible for high-speed signals

The history of your posts, oh my... But I will attempt to provide an answer in earnest.
All sane people are against an endless war. Or, any war for that matter. The only state that can be compared with an endless war is a mid-war period: the time when both sides know that the war is coming, and they live in misery, entrenching and militarizing, while the rest of human development stands still: economy is military-spending driven, birthrate falls, population flees, etc. Do we agree on that or do you need examples?
So, taking your question at its face value: the alternative is lasting peace. The history tells us that the only condition for lasting peace with Russia is either strong and decisive resistance or military alliance membership. Again, examples are a legion: both positive (Finland, Baltics, Turkiye), and negative (Georgia, Ukraine, Afghanistan, Syria, Chechnya to a certain degree).
The only path for lasting peace for Ukraine is to humiliate Russia on the battlefield. For that to happen they need weapons

Russia advantage is its large border with China. The US is not allying because of their (non) existent economy. But they'll be a formidable ally in case of a war against China.
That border is either mountain ranges (Altai), or empty steppes (Zabaikalsk), or boreal forests (Amur and Vladivostok). Either way -- the area lacks infrastructure and even roads, for the most part. It doesn't provide any military advantage, especially given that the Chinese side of the border is much better developed.
If anything, the area is not defensible against even a half-ass incursion effort from the south (either economical or military-driven), which they're actually in the middle of (the economical one for now) without realizing that.

What is a v7 UUID. Why do we need more than 1. uuid from a random seed and 2. one derived from that and a timestamp (orderable)
As it is usual in many areas of human endeavor, newcomers to the field tend to criticize design decisions that were made before them, only to re-invent what was already invented.
Sometimes it leads to improvements in the field, via rejection of the accumulated legacy crud, or just simply affording a new perspective. Most other times it's a well-intentioned, but low-effort noise.
I, personally, do it myself. This is how I learn.
