I'm still very bullish on Brainchip.
Deep learning is making a lot of noise, but it's old technology. The power/processing requirements are too high for small embedded and remote devices.
Rapid Autonomous Learning (Brainchip) is in its infancy, so will take a little while to get going, but it's definitely the future. The disruption factor is just too significant for it to be ignored.
They've kept all their promises thus far and delivered significant progress in a short time, and the advisory board alone makes me confident.

Patience is required. The hype got a bit ahead of itself, and some people got burnt bigtime, so the sentiment is low. If you believe in the technology then it would be called a perfect time to accumulate.
