also, the joint press conference between the US and the EU today is pretty promising that we don't have to worry about this, considering the "zero trade barriers" line and the fact that the GDPR is a huge (data) trade barrier...
You're mixing things up. GPRD is still there and it's mainly about privacy. It has totally nothing to do with trading, so it's not a trade barrier.
If you want to trade personal data, then that's just why the GPDR came to effect, because the EU does not want that.
You can still trade around the world, even with GPDR in effect. It's indeed quieting down, which only means that questions are answered, nobody is making a big fuzz about it anymore. It does -not- mean we can forget about it, that checks will not be done or fine's will not be given.
