Especially with computer-related hardware tech, prices tend to go down as competition increases and that the technology gets replaced with higher performing one. CD ROM burners were amazing technology, and now they are super cheap. Pentium II was super expensive too. GPUs cards... GeForce GTX 470, 350 USD into 35 USD today, in 10 years. There is no reason to believe that "AI accelerators" (which are +/- non-specialized GPUs for now) won't become cheap too. It may even come faster than expected, like this year, Apple may already announce specialized circuitry. And no, there is no need for 7T USD for that. The foundries are the same, we haven't discovered integrated circuits, just some cool software that is not different than running Grand Theft Auto in "the cloud".
