AI, Neuralink, and the Evolution of Human-Machine Interfaces

Humans have enjoyed an intimate and physical relationship with technology and how they have interacted with tools throughout time. Throughout history the tools created by people have the same two basic characteristics: tools require that a user manipulate them through some physical input, and the tool or some connected object will respond accordingly and provide user feedback via an externally observable output. For example, at the dawn of time a person might hit a sharp stone tool against a branch (the input) and then see the tool’s effect from the cuts created in the bark (the externally observable output).

Fast forward to more recent times where people use more sophisticated tools in the form of computer systems. Even these modern digital tools required people to manipulate them though physical inputs (mice and keyboards) and observe the feedback through an externally observable output (monitors). This paradigm of the directly physical Human-Machine interfaces began to change in the past few decades with the rise of Artificial Intelligence (AI) capabilities.

AI has introduced an era where computers are able to not only work through direct physical manipulation, but where the tools themselves are able to observe and make predictions about a user’s intent. For example, computer vision systems record peoples’ natural kinesthetic body movements and gestures, use AI to interpret those gestures into requested actions (input) and display the results on a screen (for example scrolling through a menu). These systems still rely on some physical input from users, although there is not the same direct physical connection. Digital assistants such as Apple’s Siri, Amazon’s Alexa or Google’s Home similarly require a physical input, although a very light touch in the form of a breath of air for a voice command.

On August 28, 2020 Elon Musk and the Neuralink team presented a live demonstration of Neuralink’s latest experimental technology – a device which can be implanted in a skull to both read signals as well as introduce electrical impulses into the outer cortex of a brain. In the presentation, Neuralink showed a video of a pig with a Neuralink implant walking on a treadmill. Predictive algorithms attempted to determine the test-subject pig’s position and motion with surprising accuracy. Although early in development, this technology offers a view into a possible future where the tools of our digital world no longer require physical manipulation for an input or an externally observable output. It is an interesting world to imagine in my mind’s eye – even as I type this observation out on my physical keyboard.

2022: The Year of the AI Image Generator

Sarah Hoffman

November 22, 2022

While 2021 was the year of monster AI language models and AI text generation, thanks to powerful language models like OpenAI’s GPT-3,1 it seems that 2022 is the year of text-to-image AI systems. We’ve seen AI art before – just last year Sophia the robot’s artwork sold as an NFT for almost $700,0002– but the tools we are seeing now let anyone, regardless of technical proficiency, become an artist, a graphic designer, or an illustrator. And the quality of the output is surprisingly good and will no doubt improve quickly.

Before the novel coronavirus swept through the world, things were looking bright for women in the US workplace. For the first time in almost a decade, women made up the majority of the workforce; 42% of businesses were women-owned; women with patents went from 4% in 1976 to almost 22% in 2019; at each level in the pipeline, the number of women was increasing. And then the pandemic hit.

Why all the Fuss about ChatGPT?

Sarah Hoffman

February 14, 2023

While most of the AI buzz of 2022 was around AI image generators like DALL-E 2, Midjourney and Stable Diffusion, the year ended with a bang with the release of OpenAI’s new text generator ChatGPT. Attracting over 1 million users just a few days after launch, the app’s performance made headlines with some even comparing the significance of the release to the debut of the iPhone.1 There are good reasons people are talking about this new technology:
