The problem I see is that IIRC in the Wave Convoy stories the trekkies had holodecks in 2011-2012, and The Jason had 'Hardlight' tech in 2015 (used in the 2nd Phobos Annual, combining force fields with standard holo-tech). While we can restrict Hardlight tech to specific items/individuals, by the point this supposedly happens someone will have come up with something like this (for general use) already.
It could have at least one of the pillars of commercial tech (cheaper, with faster and better being the other ones), thus being more widespread.
