As long as you're
1) In a position where you can make the decisions on whether or not the company should move forward
and
2) Hold the stock units that will be exchanged for money if another company buys out your company
then there's really no way things won't be fine, short of criminal investigations/the rare successful shareholder lawsuit. You will likely walk away from your decision to weaken the company with more money than you had when you made the decision in the first place.
That's why many in the managerial class often hold up Jack Welch as a hero: he unlocked a new definition of competence where you could fail in business, but make money doing it. In his case, it was "spinning off" or "streamlining" businesses until there was nothing left and you could sell the scraps off to competitors. Slash-and-burn of paid workers via AI "replacement" is just another way of doing it.
There was a time I didn’t have to do my expenses. I had someone just know where I was and who I was working for and and took care of it. We talked when there was something that didn’t make sense. Thanks to computers I’m doing it. Meaningless for sure.
Then we got email, and he retired. His successor can type and the secretary position was made redundant.
Well for starters the population has almost 3x since the 1960s.
Mix in that we are solving different problems than the 1960s, even administratively and I don’t see a clear reason from that argument why a shitload of work is meaningless.
