Twitter co-founder Jack Dorsey’s financial services company Block has announced it will fire 40 percent of staff – around 4,000 people – because new “intelligence tools” the company is implementing “can do more and do it better.”
The company announced the sackings in the shareholder letter [PDF] accompanying its Q4 earnings announcement on Thursday. The payments and crypto company reported quarterly revenue of about $6.25 billion – up 3.6 percent year-over-year – and gross profit of around $2.9 billion. The company made $1 billion of gross profit in December 2025 alone. Full-year revenue came in at about $24.2 billion, and gross profit was around $10.36 billion.
“2025 was a strong year for us,” Dorsey wrote in the shareholder letter, before posing the question, “Why are we changing how we operate going forward?”
His answer, spread across the letter and a Xeet, is that AI has already changed the way Block works, so it needs to change its structure.
“We’re already seeing that the intelligence tools we’re creating and using, paired with smaller and flatter teams, are enabling a new way of working which fundamentally changes what it means to build and run a company. and that’s accelerating rapidly,” he wrote on X.
Eh, I know this is the anti-AI instance, but reading and interpreting things like that is something you can verifiably get AI to do 90% of the time.
Because 90% accuracy is acceptable for financial institutions …
I’ve got an idea. If 90% of AI’s output is accurate, just have humans review the 10% that will be inaccurate.
(Yes I am an AI expert, how did you know)
No, it’s really not. Thus the 6000 remaining employees.
(Assuming this is a significant part of their business)
Hell USPS has been using machine learning (yes a kind of AI but not the kind they are implying) for years to do that kind of thing.
