The "80%2 figure is not from some deep analysis, the source they cite is
just some op-ed piece. And with general failure of startups being between
75% and
90% depending on who you ask (and what industry, and what country, etc), that figure would not be out of the ordinary even if accurate.
Example: Digital Twin. This is simply making a viewable physical model attached to an already existing mathematical model = "simulation" in the VR world. We have been able to create viewable models in the mechanical CAD world for at least 20 years or even more. But Digital Twin marketing is allowing companies to make it seem as though we have "new" technology and raking in tons of cash. Makes me think of the pet rock fad.
There is a little more to a Digital Twin.... but only a very little. A proper Digital Twin is a simulation running in parallel with the actual hardware (an assembly line, a building, etc) with the outputs of that simulation compared to sensor measurements of the actual environment to flag up "hey, something is not happening like its supposed to". Basically picking out the error term of a closed-loop feedback system but taking the system-of-systems approach rather than only applying it to subsystems.
But yes, 99% of 'digital twins'
sold to businesses are just "here's a copy of the CAD for your building plans, go update it to the as-build state and then keep updating it" that is never updated and is left in a drawer somewhere never to be looked at again, because the buyer has no clue what a Digital Twin actually is or why they want one other than buzzword-chasing, and there are plenty of unscrupulous 'consultants' happy to sell a company their own CAD files back to them at a tasty markup.
When everyone figures out that Large Language Models don't have
any actual utility to anyone and a bunch of accelerators are offloaded at bargain basement prices on ebay, the real winners will be those who have been training specific-task models for decades (stellar object classifiers, crop status monitors, etc) who now have cheaper iron that run faster.
