A well-known company in our industry is offering me under half a month’s salary for the engine driving Scriptable. In fact, it’s not even the Scriptable engine, it’s the more polished Scriptable 2.0 engine.

LOL.

Follow up on this:

After I told the company that our prices are too far from each other to proceed with the negotiation, they told me that they believe that I should only be paid for the time it takes to extract Scriptable's engine from Scriptable and hand it over to them, not for the time it took to build the engine.

Bullshit!

With this mindset the next company interested in Scriptable's engine should get it for free since it has already been prepared for handover.
@simonbs I’m going to try going to a car dealership and telling them I will only pay for inspection and delivery fees - since the car has already been manufactured and is just sitting on their lot.
