On paper countries can build giants without FDI, but can't build giants without industrial policy Poland can't adopt due to EU trap (which basically designed to keep west euro industrial incumbents on top) and (IMO) if Poland ever tries, FDI tap going to stop. Structurally Poland is periphery not core, allowed to prosper but not overtake, which puts ceiling. Exception being defense, but even then stepping on west euro toes.
Keyword being Strategic, i.e. industrial pillar industries that sustains entire local industrial chains / ecosystem.
It's like comparing a 6-year-old soccer player to Lionel Messi - you're looking at early signs of development, and the progress to getting there, not saying Poland is already there, but there are positive signs it is on that path.
