- cost must be reasonable, if expensive - anything over something like $2,000 is going to severely limit your customer pool. A semi-automated manufacturing line will help with this
- for good measure, a crack marketing team
Another consideration is that the BCI industry is moving insanely fast. By the time you set up a production line and start mass-producing, there might be news about a novel much-better process that overshadows your product and destroys sales. This is effectively what happened with VR in 2012-2018 when everything was super expensive; only as of recent can you recommend an Index or Quest 2 to people without fearing a huge leap in VR quality to be coming in the near future.

Eh, not necessarily, early BCIs if actually useful will likely be targeted towards people with disabilities and thus funded through private or socialized health insurance. Once the hardware undergoes commoditization consumer grade BCI will become inevitable with low price points. VR evolved slower because there was no middleman like insurance buying hardware for their customer pool (the counterpoint being Apple Watch which you have been able to get at a huge discount with some insurers).
