Deino you have been doubting the Turkish Defense Industry all throughout the 2010s and been eating crow every time. You even said this TFX Jet was fake and domestic politics, up until we saw it fly, so maybe temper the cynicism a bit.
So if we are going by prediction records I'd trust the TAI/TFX Engineers more so than your predictions. If they feel that it will be ready for export in the 2030s, think I think there is a decent chance.
Turkey already signed an export contract for Hurjet and with a Large NATO state no less, deliveries are in 2028.
