That was kind of my intuition, from what little I know about these things (nerdy culture, but tangential and second-hand at best). Tangential remark, however, I hope there's room for post-silicon / -electronics technology. We are far from some of the more advanced use-cases of computing (currently "sci-fi" but hard/real science, just hard problems in technology as well), in ways that no cleverness nor cheat (e.g. qbits) could substitute for actual processing capability. I don't know how many orders of magnitudes silicon still has to go, but my impression is that it's relatively limited physically, compared to what could be. But that's a topic for the 2030's and later, probably, hopefully. Here's to the quest for Landauer's limit!
