I wouldn't be surprised if some of franky1's concerns are true, but cannot confirm this as it is way beyond my technical knowledge and expertise in this area.
FYI, franky has been having his "concerns" for 3 years and counting.
Do you know what happened to the issues that Franky used to complain about? He no longer complains. Because they were demonstrated to be unproductive trolling. When he finds they don't work, he simply switches to newer trolling strategies instead.
If you'd believed anything Franky had stated or predicted, Bitcoin would be hugely unsuccessful cryptocurrency with all the users abandoning it in fear and frustration. But it keeps becoming more popular, and more successful.
I was hear 3 years ago (may have been posting as FunkyRes) and I recall Franky's posts, hard to forget his awesome avatar. They don't seem that different now to me. Well there is a difference, I no longer am gunho about SegWit.
I wanted SegWit because I like the idea of micro-payments but I have since come to realize that micro-payments isn't what segwit is about and can be achieved by simply increasing the block size, which is the KISS solution to the problem. SegWit has a different agenda altogether and I do not believe it is in our best interests. It adds incredible complexity to bitcoin while taking control for the transactions outside the blockchain (via lightening) and I can not condone that.
I hope you are not supporting BU while claiming segwit adds "incredible complexity".
The only thing complex here is the ridiculous "emerging consensus" BU approach. Actually it's not that complex, it's pretty simple: BU doesn't work.
Segwit does, it has been tested to hell and back. Let's get segwit already you pricks.
