Good luck with that. Europe doesn't provide the environment (neither culturally nor financially) needed for these types of companies to arise.
And if you want 'state planned' tech companies: What happened to the EU funded Google-killer again?
If Europe doesn't reform itself and makes it less punishing for people to start, grow, fail, start again businesses then Europe will be left behind.
And tbh. I don't believe Europe can reform. Because the problems are so deeply entrenched in European societies that it would take a herculean effort to change things. Something no one is willing to do.
So all we have left is old money industry. But that won't keep up as alive for ever...
