Agreed with others that 60% isn't the number, nor do I believe 2023 is the year. There was a major presentation given to technology in 2020 where they had a huge slide up that included a blurb I don't think they meant to leave in. It said "42% headcount reduction by 2027."
Plans can change, but at the very least the plan in 2020 was to reduce (USA) headcount in technology by 42% between 2020 and 2027. Covid slowed that down a ton, so they are playing catch-up now, but they still likely aren't going to seek to finish the layoffs and transition to offshore until roughly 2027 when they target having all the WF-owned datacenters closed.
That was always what this was about. Get rid of all the big, old, expensive WF owned US datacenters and get into the Google/Microsoft owned datacenters while migrating as many applications to SaaS and everything else possible to cloud based so there's as few physical servers and WF owned/managed stuff as they can get it down to.
To some degree I think this is just due to the decline of traditional banking going on in the developed world in general. I've probably only set foot in a physical bank 2 or 3 times in the last 5 years. A lot of people don't even want to use banks as opposed to credit unions now too. I think WF's plan is to cut as many jobs and outsource as much as possible to try to survive a possible reckoning on the way for the big banks.
