Yes, we are actively investing. In fact, today we announced @BloombergBeta has a new fund to invest – our fifth. Startups keep evolving, faster than ever, and we know the best way we can support them is by staying steady, a constant on which they can depend. So our new fund is…
Excited that Georgia Tech just got final approval for a new and unique interdisciplinary PhD program in "Neuroscience and Neurotechnology". Looking forward to advancing research, innovation and workforce development for next gen brain science and health. b.gatech.edu/3UQ8fRL
Let’s not forget that there’s this one cute little fleet of *millions* of terrestrial robots out navigating the world and collecting visual inputs on the daily… and rumor has it that their bipedal robot friends will join their explorations soon. 😇

How long there really is left in a software update is one of the remaining grand challenges of science.
Thank you Los Altos. When I started having success developing AI for biodiversity conservation, government policy was the missing piece for me. I learned a lot. Overall it was very humbling. I might have done a little good.
Georgia Tech is hiring in Bioengineering with a focus on neuroscience. Should be interesting for a lot of people in the broad Neuro/engineering/tech/society space. bit.ly/3QIUaU8 (background here: b.gatech.edu/3QIvgnZ)
Excited to share this paper using new neurotech and explainable AI to advance DBS for treatment resistant #depression (TRD). Team effort including @HelenMaybergMD, @sankar_alagapan and Patricio Riva-Posse. Summary thread! go.nature.com/48lmlzC @Nature PC: Mike Halerz
