Actually I kinda did mention multiple but it seems that you want to get stuck up on viewing this from a financial only perspective. I just am still trying to balance this with a generalized take as well because different space will have different needs and because we shouldn't simplify a technology that is meant to be built on. A technology that you put on your roof is in many ways much more of an end layer solution. Having been in several programs developing things like it, often there are IP it is interconnected with too that are not useless yet are still more relevant for the manufacture than the end layer for example aspects that affect aerogel design and similar aspects.

Also admittedly, part of why I keep it generalized is because I don't want to go into details about every single industry themselves because I already have wall of text. Basically to keep it simple but a desired aspect of the model advanced aerospace is the concept of an airspace that is actively ongoing in our ecosystem around us helping out in emergency systems. In many cases a drone can be communicated by with a centralized network but as the aerospace becomes more and more complex, the benefit towards having a decentralized network is the ability for each unit to much more pass data seemlesly back and forth between each other and act as nodes as part of a greater network. For those who are focused on researching the intercommunication of automation of drone, decentralization is often seen as a natural next step by many NASA scientists I have talked to and those who work on different drone related projects. The first step is of course increasingly mesh networking many devices and interconnecting via that sense creating more FANET devices that can send peer to peer information and creating a mesh network of information that way. Then increasingly the usage of decentralized native technologies like blockchain is in some sense partly to do what you actually criticized them for doing which is do what they were doing before just automating them and doing it on a decentralized public ledger. This may not be important for your project, but it affects how different systems can be built especially when we are talking about systems where there can be a temporary disconnect of the network and a reconnect such as in emergency situations. Conseus mechanism based aspects around that situation actually do potentially lead to bigger changes around what we can with say emergency fire trucks that are operating on different frequency and farther away from the city and how systems of interaction that be built in around them. As well, it more and more is becoming relevant to potentially affecting locations that are currently stuck in a digital divide as places like indigenous population are actually quite big contributors to building in the ecosystem too.

In addition, in the NFT space, you are fully right that isn't a completely new thing and I wish more people acknowledged that. I mean heck I remember when people were hoarding CD for the same reason they were talking about NFTs and crypto. In fact I find it is more people outside the NFT space who don't acknowledge that. People within the NFT space may instead use it for different community application or they may be building their own application around the technology such as my friend mirlo is around her studio based application of smartist. All of this has to work with the social systems of course, but different people see this as solving different needs like Mirlo actually see this as enabling more visibility for digital artists and the ability to create a more studio like environment for artists than was previously able to be had in the digital space. Other more use it for selling community access for example or just for selling the NFT themselves. Further more other use the NFT to automate data that so that it can be sent to doctor but never exclusively remain in the hands of doctors as well as be transparent about where it has gone and yet private giving more access attempting to create new networks around fertility treatment and automation. Interestingly even the UN has their own take on blockchain https://unite.un.org/sites/unite.un.org/files/emerging-tech-series-blockchain.pdf and of course countries like estonia use it along with x_chain as part of their healthcare https://investinestonia.com/business-opportunities/e-health/healthcare/
