Well I'm part of a small few person team- I had a junior developer helping me who left. And I literally don't need someone like him anymore because I can do anything that he was doing via AI faster and better because it's under my control. I can have a 20 minute conversation and code revision that would have taken days for someone junior to code and would have probably been not done right (by 'right' I mean how I want it to be done, not necessarily wrong)
To think the same isn't happening all over the place and will only continue is ignoring just how powerful this tech is.
And when you are out sick, can AI do his role? When you are on vacation, can AI do his role? When you leave, can AI at least help define/interview your replacement, like he could have, even if he's too junior to step into the role?
There is so much else that people do. So many details that are just being ignored because of short term 'gains' that justify ignoring so many details.
You aren't taking what he said seriously. The junior could also get sick, present management issues, etc.
If this person plus a junior represented "1.3 engineering knots," he's saying... "actually, I'm still 1.3 engineering knots without him."
When this person leaves, they go find someone else who is 1.3 engineering knots. The junior represented .3, without the 1., it doesn't matter that much. Headcount strategy shifts.
If your company can treat people as cogs this way, your company has zero value add/domain knowledge. A company's value is what it value adds, what domain knowledge/expertise it has, or cheapest price. If all you have is cheapest price, you will lose over time. You will be undercut. You won't have the domain knowledge to adapt, to see future changes coming down the path.
So the company you talk about is already in the entropy vortex. It has no momentum. It has no future. It just hopes it can keep doing what it is doing now.
