Right now, I am thinking a lot about:

• How to use seaweed in every day products
• Real world applications of LLMs
• Ecosystems, and how to build them
• Trust, and how to foster more of it

If you think we’d have an interesting conversation about these topics or something else all together, reach out (jdilla.xyz@gmail.com) or book a meeting.
