Maybe you remberered a passage about Rockwell feeling like the element talked to him ?
The element that is described to be humming with energy and pulsing sometimes ( Rockwell described the pieces of element he had as almost feeling like they had a heartbeat) is the refined version of it. We know that it has different properties in its different forms:
"The uses for it were beyond counting. Hardier than tungsten. More versatile than copper. In the right form, its ability to generate electricity and produce radiation were unrivaled. It's no surprise then that things moved quickly - impact, discovery, invention and production. All in rapid succession."
I mean the element in this form is something that seems to be something overflowing with energy so i'm not that sure if i would say it's communicating because of that.
In spite of that i would still agree with you that it's in contact in one way or another. That being said i think this only applies to the more raw, original version of it, aka the element growing on extinction (not sure about the molten element on aberration, can't say for sure if it actually does something or if rockwell was imagining things).
Thanks to Helenas Notes as a homo deus we know that it's kinda alive and it has rudimentary emotions, which kinda carry over to things infected with the element:
"What's clear is that it's merciless. Unfeeling. It's driven by base instincts and primal emotion - propagation, hunger, and hatred - and it spreads those to its shadows. Hatred most of all."
To conclude, i would say you're right about it communicating in some way, but i wouldn't describe it as some sort of "element internet" as it's much more organic, it's a bit more like nerve tracks if that makes sense ?
