That is the biggest puzzle, especially as a holder of brn.
To me there are 2 scanarios
1.One is Qualcomm has an NDA with brn and they donot want to sign a contract until the end product is finalised. Which have a lot of merit coz Qualcomm is also providing chips for Mercedes eqxx concept car, Qualcomm has signed a partnership with prophesse who is a brn partner.
2. Qualcomm had their own technology but that is a bit rare chance coz if it has something like that they will be discussing with broader market how the things are happening. I have no idea may be someone can let us understand if Qualcomm have some patents approved on that or some patents in pipeline on that.
But just in case Qualcomm lies in 2nd category that will mean either a bigger player will like to buy brn to counter Qualcomm or brainchip cannot shine as much as we expect.
If the scanario one is getting feasible that means we are going to moon and no one can stop us from reaching there.
