Ask HN: BCI + AI top resources

So recently I have decided to make a big career turn and start working on something much more important than vanilla SaaS and B2B sector

I switched to BCI. And it feels very unattainable , very hard to even approach. Of course there is chatGPT and so on. But I really had a hard time finding good resources where I can learn and exponentially grow my skills

My objective is to be able to connect my consciousness through the non-invasive BCI and merge it with LLM eventually.

I want to systematically approach it and understand:

1. What are the fundamental principles of how BCI works?

2. Who are the top people and companies I need to follow?

3. What is the current frontier of research?

4. What are the most fundamental principles I should follow to optimize the brain signal and be able to do "mind reading"?

About my background: real ML knowledge (Kaggle competitions), a lot of LLM coding & training, software engineering at saas and my own startup.
