It’s like saying you sell ammonium nitrate and fuel oil online and then saying it’s too risky to let people have computers in case they use them to make ANFO. They can only make bioweapons because you’re selling them bioweapon components! They can’t make genes at home!
And I will point out that "stop doing that" can be applied in both directions, towards AI and towards material supply.
And that this is one way, not even remotely the only way, that gene editing at home is easy.
Again, these are just facts.
Some questions...
Is it fair to restrict AI, or fair to restrict 1000 industries?
And if it is fair to restrict 1000 industries, OK, but there should be time to do so, probably? A transition period?
And if you do restrict, many such industries just make needed chemicals, which are used by endless other, non-threatening industries.
What of them?
And, this is not the only way to make genes at home.
It is a complex problem.
