True enough. Although there's some custom pieces that could be useful, like the big flat pieces used in the SHIELD Helicarrier for the runways: https://imgur.com/gallery/n5TEAhH
And Lego's designers could lend their expertise to creating some wiring routing and harnesses, or design some mounts/surrounds for breadboards. Or mounts for standard SoC boards like the ESP32 or Mega2560.
I think Apple should release a phone that you can hack yourself if you want to, so you could just write a program that grabs the screen instead of building a LEGO camera rig.
