Here is a video from 2014 of someone controlling a quadcopter with their mind with zero implanted electrodes: https://www.youtube.com/watch?v=lsraC04Mm8w
Having 10x more electrodes that stay active for a long time, attached to self powered unit under skin with low latency wireless comm link is a major step forward.
Besides that, why the pushback? Is it coming from field experts who are like, "bah, old hat as shiny new. humbug!"; disappointed futurists who expected more ("we were promised flying cars and intelligent robotic spouses, and all we got was 2000 electrodes in our brains, and 140 characters"); misMuskists; people who sense unfairness in praises lauded upon this, in their mind, mediocre achievement, echoing to them a theme that the already-anointed and, in their view, undeserving, accrue all praise, while the genuinely meritful, themselves, for example, are overlooked, yet again?
