Having worked in the IT industry for 38 years, in my last job I told all the younger IT Engineers on the team who were half my age that, what is new now, was old at one time and what is old now will be new again in the future...
They thought I was a dinosaur....
The cloud now is just a new name for a mainframe running payroll, AP, AR, GL, etc...
In between then and now you had something called Windows Terminal Services and Citrix...combined with machines called Thin Clients which were essentially dumb terminals connected to a mainframe.....
It all goes in cycles..
My home desktops are still Super Computers in these daze..
Spreadsheets, within the capability of ten year old hardware pic storage, internet text, audio, pics, and youtube videos are well covered w/o any Cloud BS.
