The bearings must sound like total crud. Or maybe they are not 3D printed. If they just printed the parts then okay, probably it's not fast but I would watch the first 15 minutes just for fun.

It's a little sad that we need to actually say this, but:
Don't be an asshole or you will be permanently banned.
Respectful debate is totally OK, criticizing a product is fine, but being verbally abusive will not be tolerated.
Focus on discussing the idea, not attacking the person.

It seems that "fully" 3D printed is an overstatement. The article says, "there’s 3D printing whenever possible". That includes printing the frame as a single piece, and the hubs. Some pieces are specified to not be 3D printed like the crank and saddle. The article doesn't mention bearings.
You could definitely 3D print smooth bearings, 3D printed metal can be very smooth after it's polished. Printing titanium is a whole different game compared to the FDM printing most people are familiar with.
