Ok, it's final step for pure digital electronics.

There might be a new type of technology in the future that makes integrated circuits obsolete

, which is a new type of IC, and I don't think most Bitcoin miner ASICs are 3DICs at the moment.

Then in the future there could be a new type of invention that is even more efficient than ICs.

Bitcoin Mining went this way: CPU->GPU->FPGA->ASIC. What's next?

An ASIC is an integrated circuit.

There might be a new type of technology in the future that makes integrated circuits obsolete

For example, right now there are [3DICs](https://en.wikipedia.org/wiki/Three-dimensional_integrated_circuit), which is a new type of IC, and I don't think most Bitcoin miner ASICs are 3DICs at the moment.

Then in the future there could be a new type of invention that is even more efficient than ICs.
