Agree to that sentiment. At this stage of digital technology, it very difficult to avoid being amused by the film/digital debacle in the 00s. At a pure technical level, photography surely has evolved a lot since the film age faded into obsolescence. However, I hesitate to declare the same has happened to the images produced.
Yes, I join you in the desire for Ektachrome Infrared. Not the latest version though, as it made garish non-subtle colours processed in E-6 chemistry (it was designed for AR-5, which no usual labs did at the time). The old E-4 version raises many fond memories, however. I'm actively trying to emulate it with my Fuji S3/S5Pro cameras and have had some success, but not gotten to the stage where I had hoped yet.
