Well, it was a long time in coming, but the Monero GUI is finally out. What's the next thing trolls are going to complain about? The 'cripplemine' is pretty much debunked, and now Bitfinex trades it, so 'but muh one exchange' is also a dead end. I guess the only thing left is "the community says mean things about scamcoins, they're a bunch of jerks".
Discuss.
There it is still lots to complain and new things will pop up all the time. Website can go down. Darkmarkets might find Monero to boring. Goverments might find Monero threatening. Monero transactions are to expencive.
How long it took to create the GUI (2 years?) will be an ongoing concern as it applies to future improvements to Monero.
GUI was under development for like half year. From spring to autumn 2016. Then it was heavily tested ( well heavily could be hard word to use here. Some software company would probably laugh at this, but for open source crypto coins projects it was heavily tested) for months as all things in Monero to prevent usual crypto stupidity. So about half year.
