Hiring the replacement ≠ finding the same or better replacement.

Will you be able to find someone in this economy? Sure

Could you fill the shoes? Much harder. Especially in the age of bootcamps, AI to complete exercises, and what have you where people went into IT for the money and not for the love of the craft, tinkering and learning.

So this is not an oxymoron: you can have 200 applicants and not a single good one to replace someone with them.
