Honestly, I don't see very much progress towards the widespread use of thin clients
Are you serious? I would bet that vast majority of end users' computers (smartphones included) are actually used as thin clients that do nothing else than access online content. People rarely use anything but the web browser and maybe a couple messenger apps, which are essentially thin clients too. Yes there are cases when people need to run specialized software that don't exist in "the cloud" or can't operate like that because of bandwidth or other limitations, but I'm sure these are comparatively rare.
Yes, I'm serious, but I admit that I was thinking mostly about desktop computing rather than mobile computing. What you are describing (Web browsing, messaging) are content consumption activities and mostly take place on Android and iOS devices.
As for desktops, I think I am a fairly typical user, and I don't think I have a single app that - overtly or covertly - runs "in the cloud". Let's see:
MS Visual Studio and
Delphi for Windows software development
Arduino and
VisualMicro for microcontroller programming
MS Office 2019 for word processing, spreadsheets, etc
Affinity and
Corel Paint Shop Pro for graphics creation and editing
Soundforge Audio Studio,
Audacity and
Pocket MIDI for audio creation and editing
Cyberlink Power Director for video creation and editing
Siemens Solid Edge and
KICAD for CAD work
All of those run on my PC, not in the cloud.So yes, I'm serious. Are you
seriously telling me that most desktop users do all that "in the cloud"?
EDIT: I've just remembered: my email software -
em Client - also runs locally. I've also just remembered that I have Messenger and WhatsApp clients on my desktop, and those will definitely be "thin", so that's two cloud apps I run.
