## 15:33 reduce employer dependence

proprietary projects own your mind share! even open source ones do, but
proprietary are the worst - the more you invest in a technology and
specialize in a particular implementation, the more that tool has mind
share over your actions.

alternatively, building universally applicable skills, generalizeable
tools or software independent of corporations is incredibly powerful -
you can keep that knowledge around regardless of the ecosystem you're
investing in because you learned in principle, not in practice. this is
the motivation for research, for System F and type theory over specific
language implmentations, for understanding the big picture - as this can
never be stolen from you. using tools that are *so* abstract is
incredibly dangerous, and that's sort of the truth in everything about
computer science - but by abstracting them at a theoretical level and
working with generalizeable ideas rather than specific technologies,
you'll never really be trapped by an employer.
