Testimonial for the Advanced Knowledge Systems in Tana, by Andrew Altschuler. I am thrilled to share my experience with the AKS cohort! Being part of this group has been nothing short of transformative. From the very first session, I felt a sense of belonging and support that encouraged me to push my boundaries and explore new ideas. The diversity of backgrounds and perspectives enriched every discussion, making learning not just informative, but also deeply engaging. Each member brought unique insights, fostering an environment of collaboration and innovation. The facilitator, Andrew, was exceptional, guiding us with expertise and enthusiasm, ensuring that everyone felt heard and valued. The lecture, about “sense making”, has been an eye-opener. Some impressions of the work of Andrew can be found and in: https://www.collider.space/new/ Overall, this cohort has equipped me with invaluable skills, boosted my confidence, and ignited a passion for continuous learning. I would say that the key parts of the cohort are applicable for any of the applications working with object orientated information streams! I wholeheartedly recommend this experience to anyone looking to grow personally and professionally. Thank you to everyone involved for making this journey so memorable!
