Was it wrong to invest in ionic 1.0

I think we all feel your pain, but I would say you definitely have not made a wrong investment. I learned a technology where the company totally redesigned it and didn't provide a good upgrade path, now THAT was a bad investment. But in this case the difference isn't all that great, and we are seeing plenty of upgrade docs/videos. Be a little more positive, m2m, and hey - you chose an industry where great change is a given.
Hang in there!
