Sentdex demonstrates GAN Theft Auto, a GameGAN-based neural network that recreates GTA V so the network itself is the playable environment. He shows the results and releases the code.

Geoffrey Hinton gives an MIT talk on what is wrong with convolutional neural networks and introduces his capsules project. The description points to the capsule network papers.

A two-minute Westworld scene in which Robert Ford and Bernard Lowe discuss whether consciousness exists. Ford argues that the self is a fiction for hosts and humans alike.

A six-minute clip of the famous speech from the 1976 film Network in which the world is described as a corporation. It portrays a world run by corporate interests.

Urs Hoelzle, Google's SVP of infrastructure, gives the 2012 Open Networking Summit keynote on how Google adopted OpenFlow and software-defined networking in its own networks. The slides are linked in the description.

A 60 Minutes segment on Luxottica, the company that owns most major eyewear brands and retailers and dominates the market. It shows how consolidation of brands and manufacturing affects glasses prices.

Eric Brandwine's AWS re:Invent 2015 session on how Amazon VPC networking works. It covers the problems the design solved, why traditional approaches do not scale, and the mechanisms used for customer isolation and VPC endpoints.

3Blue1Brown's second neural network chapter explains cost functions and gradient descent, showing how a network learns by minimizing error during training.

Geoffrey Hinton's 2025 Royal Institution Discourse on what AI has learned from biological intelligence and how it might surpass it. He explains neural networks and argues that human language use resembles what backpropagation-trained networks do.

Footage of a Minuteman III ICBM test launch and its reentry vehicles striking the Kwajalein atoll target area. It shows the missile climbing through clouds and the warheads descending.

The first lecture of Stanford's CS231n course on convolutional neural networks for visual recognition. It surveys the history and key challenges of computer vision, from the Cambrian explosion and Hubel and Wiesel to ImageNet.

A very short clip from the TV series Westworld about whether it matters if you cannot tell a human from an artificial being.

A 60 Minutes segment in which Tristan Harris contrasts TikTok with its Chinese counterpart Douyin. He argues that Chinese children get wholesome, time-limited content while the rest of the world gets the addictive version.
