> 4. The institutional knowledge is not gone, in the event of any massive catastrophe employees who previously worked at Twitter can return as “consultants” and charge very high rates to fix issues as they occur. It’s pay as you go.
What you're describing is the loss of institutional knowledge with a fantasy tacked on the side.
1) There's no reason to expect those employees would come back, even at rates far higher than Musk is likely willing to pay. Everything indicates Musk has destroyed a lot of goodwill with his shambolic layoffs, and getting people to come back is one of the situations where you need goodwill.
You're basically talking about gig-work on a shitty boss's terms. Only desperate people would play that game, and the people Musk would need probably aren't the desperate ones.
2) Any employees that come back are going to be rusty and lack the institutional of what happened after they left, so their effectiveness at immediate fire-fighting will be greatly reduced.
3) If there's a "massive catastrophe" at Twitter, do you think they even know who to call back? I wouldn't be surprised if they've lost a lot of the institutional knowledge about who knew what, at this point.
