You are creating a double bind for yourself and others by posting these types of comments. Your comment indicates you want the experience making things with it which would be amazing, but you are also speculating (based on historical evidence) that Google may "take away" the amazing thing from you later.
> I'm not trying to pick on Google for shutting things down
People usually say what they are thinking. In this case, I can certainly appreciate and respect questioning what Google's actions will be in the future, but the problem at hand is that none of us can tell the future. By attempting to do so, and creating a situation where we literally believe two conflicting things at once, we get mired down in illogical arguments that end up making zero sense. Worse, when we post those illogical arguments, others get dragged into the dissonance and end up making similar arguments that make no sense and the result of that is others get lost in the mess we made. For example:
> I think Google understands how big this could be (well, why else do they do anything I suppose?)
Do we really know Google understands how big this could be, or is that just us wishing they wouldn't "shut it down later"? Both thoughts are speculative, at best.
As for me, I have no way to know if I can trust Google will leave these APIs up for as long as I need them or will not change the methods in the APIs at some point breaking my code I've written to talk to it. The latter happens to me all the time!
I realize this comment may stir some emotional responses. All I would ask is that we consider alternative ways of thinking about these illogically binding "feelings" and expand our awareness to the fact that what we really want is our software, regardless of who wrote it, to be open, transparent, trustworthy and capable of running wherever and whenever we want it, regardless of when that is.
Obviously we have a long ways to go before that statement can be a reality. One can hope though!
