Let me explain you why I am not concerned with the future of B4x.
At least a couple of reasons.
We all esteem Erel and we read before about a "plan B" in case it would ever been needed. That's enough for me.
In addition, years ago a company named Turbo Power Software (owner of very good Turbo Pascal libraries) was acquired by someone who decided to shift their focus on a different core business and they released source code of all their libraries. This makes for a generous and well appreciated plan B, IMHO.
Another point is: if I develop a software using version x.y of B4x and the world comes to an end..well I could still manage bug-fixing and updates (to some extent) to my code as long as I have a copy of that same B4x version. Yes, I won't be able to cope with advancement and new features at the OS-level or some specific point, but at a large I will have enough time to move to a different development platform if the need arises.
About the bus.. if you're the chief architect of a very complex software, are you sure your company will survive a bus hitting you? I mean, maybe the ones that should express more concern are our customers not us.
Anyway, let's think positive. Don't sit in the cavern overthinking about the dangers out there; just go out and explore! .... good luck... ehehe
