From the article:
"Analysts and investors have favored disposing of the business, which they said didn't add much to the chip sales and was too dependent on the shrinking PC market."
In shared computing environments (the cloud) and in small-form-factor networked computing (IoT), creating new security mechanisms which may require hardware/software co-design is the future. The statement above pretty much ignores this, hence my comment.
The sort of thing I am referring to is already present in hardware acceleration for encryption and Intel's trusted platform module (TPM), the latter causing some controversy for being a closed system which might be doing evil things.
Breaking these two apart is a short-sighted business decision. It is not the sort of thing a far-sighted, research-driven company would/should do.
