I'm not sure what experience in "personal computing" would entail as opposed to specific systems like Kubernetes. You could find someone with 40+ years of experience in Unix, C, or writing 6502 assembly code, with varying degrees of relevance to modern day work. Someone who has 40 years of experience with the 8051 or PIC microcontroller could conceivably be useful today, so if you wanted your grizzled old sarge, you could have them, assuming you were willing to pay enough money or had an interesting enough project.
