I get what you're saying but every single initiative this government has taken to grow the economy in specific sectors (tech, green energy) has been a giant failure and a ridiculous waste of money. The only real way to attract international capital is through talent (we have, for now - cost of living is a problem and is going to be a bigger problem going forward) and competitive tax environments (we don't have).
The battery production endeavours can work. We have the technical expertise and access to certain mineral resources.
Electric car manufacturing will be so so fierce. I dunno…
