recently there has been major progress into the VP=?VNP problem for algebraic circuits originated by Valiant, inspiring some optimistic outlook on its eventual or imminent resolution.
what is an outline/ overview of an intuition that VP=?VNP is connected or not (closely?) connected to the P=?NP problem?
am looking for "not complex" or "straightforward" sketches or constructions, not necessarily "rigorous".
 Recent Progress on Arithmetic Circuit Lower Bounds / Ramprasad Saptharishi, Bulletin of EATCS
The field of arithmetic circuit complexity has lately seen a flurry of results. Several of these results are centered homogeneous depth four circuits, and come tantalizingly close to separating the algebraic analogue of P from the algebraic analogue of NP.
