# The (idea) valley of death
The Valley of Death is a concept that pops up repeatedly in discussions about technology development. For a good short article on the Valley of Death and its relationship to technology readiness levels, see [[Technology Readiness and the Valley of Death]]. The term is [[Nebulous]] and overloaded, but it always refers to a situation where there is secretly much more or different work than you’d expect between a development stage that feels “complete” and its natural next step; often, this is between a proof of concept and a prototype or between a prototype and a manufactured process.
Another frame is that ideas in the valley of death:
* aren’t novel enough to publish and require too much coordination between disciplines or with industry to exist in academia
* not sufficiently product-focused to build a startup around (yet)
* Too far off the status quo to go anywhere in a corporate R&D lab
Generally this covers [[Technology readiness level (TRL)]] 3-6
Things that are too high risk to be funded on their own but a portfolio of them is worth funding.
