IBM says it has made working versions of 7nm chips
Wow, 7 nanometer is incredible! I wonder how small they can get silicon / silicon-germanium based chips before we have to resort to other techniques such as light processors (since light can be closer and even cross each other without issue). 10 nanometers that they're introducing next year is also incredible, at least to me since I'm not a hardware engineer and can't imagine how difficult manufacturing these are.
