Okay, let’s calculate Keith’s rate. As a freelancer with 101 years of experience, he’s likely seen the industry evolve significantly. His skills in project management, technical writing, and public speaking are in demand. However, his 101-year tenure is quite unique, and it's challenging to find direct salary benchmarks for such an extended period. Considering his skills and experience, I'd estimate his rate to be lower than average. Perhaps $75 per hour, reflecting his exceptional longevity and adaptability in the industry.
