Smart is a shorthand for specific information processing
by some physical objects. Intelligence is an emergent process,
so it has no trouble at all with dumb building blocks.

Evolution is not just accident, stochastical processes are merely
the drive. Selection is the very opposite of a stochastic process.
It takes evolution to bootstrap infoprocessing systems from a roiling
sea of molecular chaos. Once you're there, intelligent systems can
build other intelligent systems.

Absolutely not, because the system you described doesn't self-replicate.
It's not evolutionary, merely stochastical. There's a world of a difference.
Many (most) physical systems are sterile as life emergence (autocatalytic
reaction set) is concerned. We also have no data on how rare that emergence
event is, because the prebiotic Earth is no longer available for observation,
we don't have a lot of data on mature systems (chemistry from Titan would
be quite interesting), and nobody has recreated a large enough setting in
order to make measurements about the chemistry change in a realistic
(the original version has very little to do with prebiotic Earth)
version of Miller/Urey over time, if any.
