They are being made. I have a four node network already in my suburb. There is a software project that is written in Python that essentially turns lorawan nodes into BBSs similar to briar.
Maybe ham repeaters but when we are talking lorawan they will have a hell of a time taking the networks down that are already established. Just in my suburb we have more than 6000 nodes because of the helium network.
A good use of briar is having it on your phone already so that during a natural disaster you can connect with others that already have it at community relief spots. Keep it just in case and it will come in clutch when you need it most!
What will happen when company A implements algorithm X based on AI output, company B does the same and company A claims that it is proprietary code and takes company B to court?
When I was in Bangalore in 2018 they wouldn't even allow anyone into the entry hall without a boarding pass and passport. Security was more tight back then compared to how you describe it now.
Single-digit-nanometer-node custom ASICs aren't really required to achieve this. Although there is higher latency this can and has been done on FPGAs at a company I worked for which designed and built custom AVOD systems for private jets and helicopters.
There are so many companies that I am sure countless individuals have come along and have solved a problem for themselves that many other customers probably have. These solutions hardly ever surface.
I for one was upset when I bought a HiFi amp from Cambridge Audio (CXA-81) and it came with an IR controller. The only way to be able to control that amp through the app is by means of a DAC which costs another couple of thousand dollars. I refused to accept this as my solution. I wrote a web server that used a Raspberry Pi Zero W and an IR transmitter along with a rudimentary Android app that had a series of buttons which corresponded to the functionalities I needed.
Even using the client's keys it would be a good idea to give a disclaimer that their key may be stored (If that is the case) and can be accessible through nefarious means. People are very susceptible to phishing attempts etc. and this sort of business model (where you have the client supply the key and store it through the browser is a slippery slope.
Previously, organizations with mission-critical workloads lacked access to important cloud and AI capabilities when in demanding edge environments, including those that present unique challenges and requirements.
The value comes from the value of selling ads and knowing everything about the product. In this case the viewer. Value prop for building the ability to still have insight into your product is there. It captures all the people who think they are clever by not connecting through WiFi and not understanding that it can be done over HDMI.
