Update, 12/7/21: As an experiment, we're trying out a longer-running Open Thread that isn't refreshed each month. We've set this thread to display new comments first by default, rather than high-karma comments.
If you're new to the EA Forum, consider using this thread to introduce yourself!
You could talk about how you found effective altruism, what causes you work on and care about, or personal details that aren't EA-related at all.
(You can also put this info into your Forum bio.)
If you have something to share that doesn't feel like a full post, add it here!
(You can also create a Shortform post.)
Open threads are also a place to share good news, big or small. See this post for ideas.
Thanks Aaron, I will make sure to include this information but hopefully this will help in the meantime:
Non-invasive brain stimulation is any method of causing brain activity to change without surgery. This can include using electrodes to apply a small amount of current to the scalp with a headset like this:

Creating a magnetic field in the brain with a device like this:

Or by using ultrasound waves with a device that looks something like the image here:

The electrical and magnetic stimulation methods are well established with decades of research covering tens of thousands of participants and proven safety profiles. The magnetic method is too bulky for a consumer headset, and the electrical method has issues with reliability across subjects (my research plays a small part in helping to address this.)
The ultrasound method is more new, but with the promise of much more accurate stimulation. Without going too deep into the technical challenges that remain I think an electrical stimulation based headset that increases intelligence significantly could be available to consumers within 5 years. With an ultrasound-based headset superseding that once the research is more firmly established.
