But it can actually take that long.
Reasoning is that it's a complete split from the status quo when it comes to compute. Look at quantum computing. A project that's expected to take upwards of 40 years before it becomes usable by the public. You might think that 20 years is a long time, but when you take in the consideration along the entire thread of manufacturing from schematic to product, it's a normal amount of time. Think of laying roads, rails, transistors, and the Von Neumann architecture. All of these took a massive amount of time to come out with a feasible product.

The explicit number "20" shouldn't be taken too literally anyway. It's more of a statement that things take a long time. And even with the pace of computing a la Moore's Law(not even a law), it will still take a long time to implement an entirely new architecture that is enough for the mainstream to embrace. Edge AI is definitely the future. It makes zero sense to have fully cloud-based AI as our only access point. This is why I think BRN has a good shot at capturing market share.

On your point about being a tech investor - this is also an infrastructural investment. It's best to keep that in mind when looking into things such as neuromorphic computing. A field that is still extremely nascent and is in dire need of further investment. Much like all bleeding edge concepts.

Tl;Dr: this is a paradigm shift in computing and BRN is a company actioning a concept. It's a risk and expecting immediate early returns on such a concept isn't wise
