* Advances in hardware have driven renewed interest in deep learning. In *2009*, Nvidia was involved in what was called the "big bang" of deep learning, "as deep-learning neural networks were trained with Nvidia graphics processing units (GPUs)".
* Johan Oskarsson, then a developer at Last.fm, reintroduced the term NoSQL in early *2009* when he organized an event to discuss "open-source distributed, non-relational databases".
* The [Bitcoin] currency began use in *2009*, when its implementation was released as open-source software.
* VR 2012?
Obviously all of these ideas existed before at various stages of development, but it makes one wonder where all of them would have been if the printer was started.
