Research frames computing's physical limits across energy, memory and communication

GoKawiil's interpretation of the reporting above, not reported fact.

The comparison suggests that communication technology may be the first domain where classical and quantum approaches converge, since classical interconnects are becoming more energy-efficient per bit, approaching the regime where quantum photon-based interconnects already work. The gap in memory density illustrates that DNA storage's barrier is practical—cost and speed of writing—rather than a physical limit, which could imply future breakthroughs are about engineering rather than physics. The author's own framing cautions that vast theoretical gaps, like the 35-orders-of-magnitude figure, may not translate into near-term practical advances, given decades of stalled promises around reversible logic, quantum computing, and DNA storage.

• DNA can theoretically store a bit of information in about 30 atoms, far denser than a 125-atom theoretical minimum.
• Nvidia and Broadcom are already shipping optical interconnects integrated directly against silicon to reduce energy per transmitted bit.
• Communication technology sits roughly a million times away from the Holevo limit, the point where classical and quantum interconnects may converge.
