7 years, page-118

Just to elaborate more on the comparisons and roadblocks a new discovery can face with lack of peer support and lack of recognition

1. Alexander Fleming discovered penicillin in 1928
2. His paper on the topic to medical research club of London was met with little interest and even less peer enthusiasm
3. It didnt start being used to cure disease till the 1940s
4. In 1945 Fleming got the Nobel prize in medicine

With brainchip we are at step 2 equivalent, if this all plays out as claimed
7 years since the patent means nothing imo
