"Gate-all-around has several manufacturing challenges, and the cost is so high that it’s not clear how many chipmakers will be able to afford it. Fortunately, though, it’s not the only option on the table. Advanced packaging and new device architectures will almost certainly play a bigger role for current and future devices.

Still, no one technology can meet all needs. So at least for now, the industry likely will embrace all of them."

I’m trying to find the articles from 2017, and 2018, but this looks strikingly similar to what Intel was attempting with its 10nm gate designs.
Edit:
Found it, it was 2015 had to go back further. They called it Lateral Nano Wire.

We know that 10nm turned out well for Intel. Just need to downsize it a little and they're back in the big little gates game.

Intel has been churning out 10nm parts for a year and a half. And it's still more dense than TSMC's 7nm.
 
intel already hired tsmc for cpu production.
It shows that they are not relevant anymore.
many kinsfolks, managers, little of real engineers.
