The author probably didn't read Tim Urban's WBW article[1]. Elon Musk never claimed that we were going to have telepathy n a few short years but rather that he was hoping that he would have some sort of BCI that would also be used by people who don't have some sort of disability.
"I think we are about 8 to 10 years away from this being usable by people with no disability … It is important to note that this depends heavily on regulatory approval timing and how well our devices work on people with disabilities."
"And Mark Zuckerberg gave a timeline of about 25 years. Mark Zuckerberg said: “I would be pretty disappointed if in 25 years we hadn’t made some progress towards thinking things to computers.”"
So I think the whole article has a clickbait-y theme, I would expect something more objective from the MIT Technology Review.
Finally as the author said Musk has indeed missed the deadlines on his achievements, but nonetheless also he manages to go through with his plans, both with SpaceX and with Tesla.
So even though I don't expect the neural lace in "a few short years" I think it will come eventually.
