I do hope you're right, but I'm quite skeptical. As mobile devices get more and more locked down, All that memory capacity gets less and less usable. I'm sure it will be accessible to Apple and Google models, but models that obey the user? Not likely

As state of the art machines continue to chase the latest node, capacity for older nodes has become much less expensive, more openly documented, and actually accessible to individuals. Open source FPGA and ASIC synthesis tools have also immensely improved in quality and capability. The Raspberry Pi Pico RP2350 contains an open source Risc-V core designed by an individual. And 4G cell phones like the https://lilygo.cc/products/t-deck-pro are available on the market built around the very similar ESP32. The latest greatest will always be behind a paywall, but the rising tide floats all boats, and hobbyist projects are growing more sophisticated. Even a $1 ESP32 has dual 240mhz 32bit cores, 8Mb ram, and fast network interfaces which blow away the 8bit micros I grew up with. The state of the open-source art may be a bit behind the state of the proprietary arts, but is advancing as well.

It's really fun to have useful hardware that's easy to program at the bare metal.
