Quantum entangled communications that are impossible to evesdrop on exist now, cloud computing is the money machine that allows Amazon to keep expanding, virtualisation is used by effectively every company using computers at scale. (blockchain, I'll admit, was pretty much all hype and vapourware other than laundering drug money and allowing speculation)

Just because there is marketing hype around a term doesnt mean there isnt anything of value there.

For someone who has “been around the block a few times” you seem to not understand just how incredibly revolutionary “cloud” and “virtualisation” were, and how they did revolutionise the tech world…..
