That must have been before my time, I wasn't aware of the motivation he provided.
EDIT: Just looked at his Patreon page. I can't see the 9000 milestone, but an earlier one pretty much showcases his attitude:
"2000 Patrons:
Animation goal.
I'll buy a dedicated animation PC. That's right, one powerful PC fully dedicated to rendering animations. This means that each update will include more and/or longer animations. "
No mention of speeding up development times there, but I don't know where to find his hype for the 9000 milestone.
I'll give you an example of an even more depressing situation.
A TV show takes twice as long to come out with the final season (2 years instead of 1), there are only 6 episodes (although each episode was variable length - not the typical 60 mins), and it still felt rushed. Could it be I'm talking about GoT...
