A telling quote from that 1998 article:

"
It will be 2005 before a computer will attempt to simulate a protein molecule
folding into shape. A new supercomputer, Blue Gene, costing $100 million, will
be equipped with SMASH (simple, many and self-healing), which will dramatically
simplify the use of instructions carried out by each processor. Instead of a
single microprocessor on a chip, Blue Gene’s chips will hold 32 processors and
about a million microprocessors, so it will perform one quadrillion (10 to power
15) operations per second, or a ‘petaflop’. Even then, it will take a year to
simulate an average protein folding, a process that’s complete in split seconds
in the body.

100% correct.  So different that entirely new algorithms have to be devised for
even what we now consider the simplest things.
