“I think we're still far away from having something that works that well.”
“Tools like rea are also becoming more popular.”
“It's surprisingly powerful.”
“what you're promoting is even worse than theirs”
“which is a good place to start”
“this one particular suite of clone products is exactly menu by menu, keyboard shortcut by keyboard shortcut and feature by feature a pure clone”

“it's a lot better quality than a lot of AI decomps I've seen”
“it's probably cheaper and more time-effective to use something that already exists and does the job”
“It's considerably faster than their apps (at startup) too.”
“REA is probably great for personal apps and for abandonware, but I think if you publish the results and it's found to have decompiled the original proprietary sources in discovery, you might be in for a bad time.”
