## What Jamie wrote

I like the basic concept here that the "lock in" cost of a solution is more complex than just the migration expense. However, I would also add to this that migration cost tends to trend down over time. So, in addition to the opportunity gain referenced here, I think that you compound that on a shrinking migration cost as time moves forward. Why does migration cost shrink? Because software gets more sophisticated over time, and solutions should get easier to replicate. Over a very long time that may actually go back up as the software becomes brittle, but in the first several years I would argue it trends down.
