Some of those copy/pasted companies (Criteo, Blabla car, Vente Privée...) actually managed to be quite successful.
As somebody who prefers to work at a lower level my main problem is that we've lost (or are rapidly losing) most of our savoir faire when it comes to the hardware side of things. Could we even make a competitive CPU from scratch in Europe anymore or are we doomed to integrate American and Chinese IPs and ICs? What are the security risks if we just run "black box" foreign-made chips? Can we really trust Intel and AMD all the way for our critical infrastructures?
