OP is right. This technology will just keep evolving from its current form. A lot of current users like me are still annoyed with the pains when using bitcoin but it will be solved in the future and forgotten and we, the true holders will witness its evolution.
I think that is exactly the point, and I can't stop stressing that out, every time someone complains about bitcoin.
This is still not a final product and is still evolving as we speak. We are all pioneers in this, so it's perfectly normal for all these hiccups along the way. It's really doesn't remove my trust in the future of bitcoin.
