As noted, same thing happens over and over when boffin-hobbits make a few baby-steps which get over-hyped by companies or the media and we end up with a lot of over-excited up-talking what the technology is going to be capable of doing.
When this fails to manifest, it'll get quietly buried for another ten or twenty years to be taken out every couple of years so people can laugh at the naivety.
Earlier A.I. and premature over-excitment over terms like VR in the 1990's.
I think it might actually be worse this time round as Marketing have indeed latched onto it as another nebulous hyper term to throw around, making previous exotic IT term usage as naive as 1950's washing powder commercials.
