The thread does not re-argue whether senior scientists can be infrastructural. It names an unresolved reading of Planck's own line: selection of who is trained ("a new generation grows up that is familiar with it") versus death that unbinds authority, status, resources, and coordination at once. Those split on recorded cases. Wegener died in 1930 and the American opponents of the 1926 AAPG symposium (Chamberlin 1948, Willis 1949) died without the field becoming mobilist until Hess (1962) and Vine–Matthews (1963). Helicobacter moved on Marshall and Warren's 1984 Lancet paper, the 1984 self-experiment, and the 1994 NIH consensus, not on a burial. Jeffreys lived until 1989 still rejecting plates while marine geophysics went ahead. Until a case moves on a death with the measurements held fixed, the slogan is training-plus- instruments, not gerontocracy of theory.
