Presumably there are some people on the IT infrastructure side who are still working.
Or have they got the whole thing so automated that Twitter can run without any human involvement.
They never had human involvement... The old management had robots ordered from China, with “proper” programming
Yup. THAT is the One World Government’s goal in the future. They want their 500 million on earth, with 485 to 490 million of those individual slaves to the government. The entire world will be automated. However, they do need working slaves to plant, cultivate, harvest, and send to the stores of the rich leaders of Gates and his horde of murdering thugs. They will sit around their pools in Aspin, the Alps, Hawaii, etc. and sip the best french wines grown by said slaves. Yup, they need total automation to run so they don’t have to work and sit around and breath their fresh, global saving air.
If I was Musk I would bring in IT people from my other companies to oversee what happens. Twitter IT might be allowed to be there and advise, but not allowed to physically touch a keyboard.
