Ah ok I wasn't aware of this. I thought it was spot on.

And yeah I hope we can easily order small batches of ICs (at big pitch of course) in a few years, in a similar way to how creating PCBs has become so simple now.

I mean I remember how much of a PITA it was in the 80s. Drawing on overhead sheets. All the acids and other chemicals. Drilling. And now we get super-accurate 10x10cm boards dual-layer, drilled, soldermasked and silkscreened for a buck a pop with a minimum of 10. Wow. I really hope this trend continues down to the scale of ICs (or that FPGAs simply get better/easier).

By the way, emulating a CPU is pretty easy and very accurate anyway. The big problem with accurate emulation is with some of the peripheral ICs which used hard to emulate stuff like analog sound generators.
