In my defence the new bit was "in IT" not technology generally. IT is the operation of information infrastructures by major enterprises. And the timeline was 30 years. Laptops were very, very, very uncommon 30 years ago!

Cloud computing isn't just shared servers - it's a shared application infrastructure. It's extremely different from the old mainframe model.

I have to say I do think that operations could be better without new silver bullets, but the scale and pressures on IT and business operations in general are dragging them to a precipice. Things are now so complex and demanding that at some point we may well see major organisations fray and disintegrate because they just can't run themselves anymore. Something close happened with the cyber attacks on Maersk and the NHS a few years ago - but from what I've seen it's quite possible that someone big will get themselves into such a tangle that they suffer a complete operational breakdown without an attack.
