Yes, but:
1. That's not Moore's Law, which is specifically about density.
2. When you aren't getting density increases, your processing power / memory size / whatever increases linearly with die area. We've been used to living in an age with regular process node shrinks, meaning that more and more powerful computers don't end up being more expensive. Sometimes the cost goes down while the performance goes up. We're seeing the end of that right now.
