I'm not an expert in this field, but it seems like any mind reading we can do today with ECoG we can do tomorrow (or next decade) with EEG; the invasive electrodes make it easier, but we should be able to read signals non-invasively with better clarity in the future. When you say it won't be cheap/easy "any time soon," what does that mean to you? 10 years? 50? 100? The privacy concerns seem valid to me, though I'm not saying the sky is falling. I look forward to thinking text into a computer. I'd be extremely skeptical of any company demanding that I put their hardware on my scalp, but I'd be willing to put my hardware on my scalp and present some limited interface between it and the company hardware. Also, I expect the problems with invasive surgery to decline.

I would be moderately surprised if you could infer ECOG at 150 wpm via EEG. That would be roughly akin to claiming that, because you can infer water flow in an pipeline to Los Angeles from magnetometers welded to the pipe, you can do the same thing using a constellation of geosynchronous satellites. There's a lot of things happened in between the pipe and outer space. Similarly, there's a lot of things happening between the arachnoid mater and the surface of the skin: innumerable liquid-solid interfaces of varying types being a major class of issues. The electric activity in the arrector pili, the galea, etc. Distance, bone, etc.

  I didn't say "everything," this is kind of a side-tangent but in particular I imagine writing to the brain might be really difficult to do non-invasively while keeping per-write side-effects as low as invasive alternatives. I disagree with your projections of the future, and expect that geosynchronous satellites will be able to infer water-flow in a given (non-shielded) pipe within the next 30 years. I could be wrong.
