You don't really have to push Argentina as a high-tech hub for online marketing and logistics, software development, fintech, among others; Argentina is already all of those. If there are Argentinians capable of creating startups in AI and ML, and I imagine there are, Argentina will become a hub in those areas as well without any incentives from Milei.
Low-regulation spells "dumping" for me, bottom-fishing the pond for projects rejected by other countries and blocs. It's not the way to go.
And this, from the article: “They would need to see Argentina get rid of its [strict capital controls], and pass long-term economic reforms before putting down money,” said Ignacio Labaqui, a Buenos Aires-based senior analyst at risk consultancy Medley Global Advisors. “That process is just barely getting started and I would be cautious.” Does any of this sound likely considering we're 6 months in and President Jetsetter hasn't passed a single law yet?
