Physical Limitations of OOPS (skip?)
OOPS should scale in unbeatable fashion. Limits?
Resets all states; so we may use reversible computing (Bennett, 1982): no fundamental heating problems expected.
Computing power by cost grows 1000-fold per decade (Moore)
Bremermann limit: 1051 operations per second on 1032 bits for Lloyd’s (2000) ultimate laptop (1kg, 1l).
Sun-sized OOPS (1030 kg): given previous solutions, will find solutions to new problems requiring 200 bit programs running for, say, 1020 steps ( ? Solomonoff’s “conceptual jump size”)
More than that will remain impossible: light speed limits acquisition of additional mass through function quadratic in time.
But even modest speedup factor 109 expected until 2030 very promising (with grid computing or NEC Earth Simulator we could already solve our 60 problems within a few seconds).
