I see the ‘One True Engineer’ has shown up. Comparing bridge building to engineering antibodies is absurd, a x10^12 error in scale. A better comparison would be to semiconductors, where you will find many ongoing failures, even in current production runs. Also, the mere fact that it is difficult to engineer something doesn’t mean it isn’t ‘engineered’, another absurd contention. I don’t work in biotech, and also don’t take kindly to being called delusional or a liar. The actual bottleneck isn’t human trials it’s better drugs, and even if trials were the bottleneck, why have you decided that bioengineering needs to be able to design a drug with guaranteed > X% chance of working before it gets to be called engineering? Also, you are ignoring all the other industrial, environmental and agricultural applications of synbio.
