> I understand the toxicity of lead, but I wonder if the hand could've been more targeted. Does lead in bearings really show up in the environment?

Part of the issue is in manufacturing. It might be hard to prevent exposure of employees to lead dust if they’re machining parts containing lead even if the final product isn’t too risky.

If someone said "having taken many doses of basically just water in my life, I can tell you that homeopathy is not 'bunk'" would you find that to be a convincing argument?

Which Bell Labs? Are you still in the area? I’m minutes away from Murray Hill and a lot of what you’re saying resonates with me (~10 years into my career and starting to lean into what I previously thought was weird).

I’m quite late here, but if you want a diagram you can ask the LLM to output Mermaid syntax and then paste that into Excalidraw or something else that can render based on Mermaid.
