around 2025 with an inability to go below 2nm. Such predictions are "wild guess" but I've not yet seen an expert strongly bet in favor of a complexity/cost wall. If I remember correctly, a silicon atom and the spacing between them make ~0.2 nm If you think that starting at 2nm we are getting closer and closer to this physical limit is utterly wrong: Because what we call 2nm is not a 2nm transistors. Today transistors (7nm) have some parts that are on the hundred of nanometers! What I would like to know is how much reducing those parts will bring performance? Maybe those parts of a transistor actually matters far less?
