Not all hard fork necessarily heal, there are currently 3 full-time developers working on Bitcoin, if this monetary system would be developed by say, Oracle, with +200 programmers working on it fulltime we wouldn't have that risk.
What are you trying to say? That the quantity of developers matters here? Something could go wrong even if we had not 3, not 30 but 300 people working on it.
The problem is that people panic when a hard fork is about to happen/happens. Else it should/could go smooth.
@OP Why is this relevant? This gives some people even more reason to spread FUD.
The quantity of dedicated developers matters here, if there were enough skilled developers the hardfork would be detected before it occurred.
