I wonder how it compares to vegan protein in terms of farming cost/sustainability. The blend I use is pea protein, brown rice protein, pumpkin protein, flaxseed powder and quinoa flour. It's about 23g protein per 35g and around 135kcal per serving I think, so it's not like I'm used to whey/soy isolate which are more like 90% protein.

If you farm crickets or cockroaches, sterilise them, dry them and powder them to flour you get about 0.75g of protein for every 1g of insect. If you make protein from whey, you get about 0.008g per 1g of whey. Give or take, averaged out from a few different figures I found.
The only reason why protein powders are higher than 75% protein is the complicated refining process they go through.
I do wonder how easily insect production can be scaled at the moment though. Given that its far better for the environment than the dairy/veal farming that produces whey powder and that its much more concentrated source requiring less processing,I can only think of two reasons why it hasn't been done on a large scale:
