Intel shows off its heart of glass
 

Seems like the real thing, but I was so blind

Intel has shown off its initial work on developing a glass core substrate and associated chip packaging process and says it could be used by the end of the decade.

Chipzilla plans on introducing glass core substrates to its products in the second half of this decade, allowing it to package chips in more complex and ultimately higher-performing configurations.
