I have some concerns.
The terminator gene as you mentioned is one.
The forced change to traditional practices of seed collecting is another. So you have to buy new seed every year.
The fact that the policy is one directional. Once you go GMO you cannot go back. If you do and your crops are polluted by GMO genes from your neighbours then you get sued.
The significant drop in seed diversity from seed banks. Many of which are now owned by Monsanto and other GMO producers, so have no interest in supplying none GMO seeds. This could lead to a massive crop failure at some point which will make the dustbowl years seem like a walk in the park.
The growing resistance of weeds to Roundup and other pesticides thanks to gene migration. This is great for Monsanto as you need to but more Roundup just to kill the weeds.
The fact that politicians are taking bribes to peddle GMO as our only solution. If they are so essential then it should not be tolerated that a company can patent the food chain.
The real benefits would be better drought resistance or tolerance to bugs and these should be the equivalent of open source in that anyone can use them. Also if these genes get into weeds they will not threaten massive pollution from excess pesticide usage.
