The impossibility claim is taken out of context. This was about M-Systems x4, which was not 4 bits per cell, but 4 bits of information encoded into 3 bits via charge and cell position. The important portion of the claim, quoted in the article, is:

I tell you that to do what M-Systems says it can do requires flash manufacturers to produce a new flash with sixteen layers.

But no, what M-Systems did DID NOT require sixteen layers. Because it was a completely different beast. You misquoted the article by adding your own "[4 bits per cell]" to the quote of impossibility, which is not what this person said. In addition, he didn't say it can never be done, but clearly meant can't be done in the then current environment with then current technology. He said that in the context of M-Systems saying they can achieve something now. The problem was this person couldn't see alternate ways of achieving what M-Systems said they could achieve and in fact did achieve.

Here is the actual quote from the article you cited:

“As a physicist, I tell you that to do what M-Systems says it can do requires flash manufacturers to produce a new flash with sixteen layers. I don’t care that people say that this is possible and could happen. I’m telling you - and remember this well - it’s impossible to create such a flash. Period. No tricks or tall tales. Furthermore, if someone knows how to make a 16-level flash, which I reiterate is physically impossible, then we can create technology enabling eight-bit storage in each memory cell. But as I said, it’s impossible.”
