Supersonic jet engines, rockets to the moon, nuclear power plants, etc. etc. all have become more expensive. Superconductors were discovered in 1911, and we have been making them for as long as we have been making transistors in the 1950s, yet superconductors show no sign of becoming cheaper any time soon.

There have been plenty of technologies in history which do not in fact become cheaper. LLMs are very likely to become such, as I suspect their usefulness will be superseded by cheaper (much cheaper in fact) specialized models.
