Longterm commitment to plans.
It makes no sense to support projects short term, only then to hand the developed fruits of labour over to those capable to longterm commit to development. This is also the most valuable trait a government can bring to the market, as it is a system usually optimized for exploring local optima, but incapable to traverse the ridges of the research landscape by itself to new "hunting grounds".
In germany, a semi-conductor industry was existing and was given up, as further development would have needed propping up by government. Solar was developed and then fed to the wulfes locally, as entrenched energy providers sabotaged the support the young industry would have needed against chinas cheap manufacturing. And this pattern has played itself out over and over in western markets.
Shortsighted entrenched interests sabotage "new Players" who venture to those capable to commit.
So even, if at this moment, all parties agree to commitment, how longterm will this commitment be. Why should someone migrate from Taiwan to Canada, only to participate in a re-enactment of a short term "desert-flowering" of a chip industry?
Nobody would try to make a career on such shifting grounds. You cant built a cathedral on sand.
