That said, the fact that it's potentially problematic doesn't make GMOs safe. It just means they're both potentially unsafe. I don't know enough to say.
By incremental gains, I meant that GMO crops will at best add some percentage growth to total food production. This will be partly a wash, as increased food tends to increase birth/survival rates. Our food boom has helped create the population boom.
So on balance, GMOs will provide a benefit, but it is unlikely to be a kind of 'end hunger forever benefit'.
Meanwhile, the system accumulates hidden risk. Once food supplies are created, we become dependent on their persistence. If anything unforeseen and catastrophic happened that lopped a percentage off world food production, we would be ill placed to bear the shock.
