Then you are not laying off because of cars. You are laying off because there is no market for what you are selling and you are not able to find new customers.

In other words, the business is not doing well

I'm not saying Atlassian is or isn't doing well, but your market isn't going to infinitely expand, nor expand at the rate you need to keep up with your costs.

If you build cars and you replace people with robots, you might fire those people because those robots allow you to keep up with demand with less people. Your business is doing fine and well but you just need less people to do the same output. Better yet those robots might even produce more than what your demand is and therefore even if demand increases your ability to supply with less people still exists.

Businesses will always look to do the same output or more with less cost irrespective of whether the company is doing well or not. This is why we have also seen "AI layoffs" across companies that have had very good financial positions or even record sales.

The proof is in the pudding if AI actually improves productivity of those left over to justify it. But sometimes simple analogies can be rebutted by other simple analogies.
