First off im no pro, not a programmer, or a computer science major, just a computer security enthusiast. so heres my two cents feel free to disregard it IMO: If the AP is vulnerable to WPS attacks and your close enough Reaver works fine, and is quite a bit simpler than aircrack, and in ideal conditions a WPS attack is almost certain to be successful, whereas your dictionary bruteforce attack may never find the proper password for the AP, if its not in your dictionary list your SOL, and with WPS pins i think it something like 11,000 possible combinations? So my answer IS NO its not dead. Its effective for the right target. Although you might not find a lot of AP vulnerable to this atack if you do come across one, and lets say have permission to perform this action its a good choice. Not to mention I love how once you start an attack you can stop it, leave go home come back the next day, and resume right where you left off.
