Yeah... having multiple trillon dollar companies doesnt have any advantage at all... High paying jobs? Taxes? Brain drain? No getting your citizens data exposed to other countries? Nope, nothing.
It's more of the same historical shit, wealth concentrated into a few individual with their cast around them, living in their bubble. History is full of stories like this and it never ends well.
Trillion dollars companies are not an achievement, it's a symptom.
Strictly use Meta as an example, since the HN crowd loves to bash them, during the same two decades they've released Presto, PyTorch, React, llama. Can you see SOME advancements?
