It is rather clear to me that yazzku is saying that the programming required to pull of what the R1 does falls well below what Rabbit promised their customers. That this is such a bullshit design that we can infer that the entire product is a scam, because if they were serious it wouldn't be so obvious that no work into actually making a useful product.
Yes it is. Simple as.
Please don't gatekeep something as casual as writing code. Good lord.
To me it has nothing to do with size or complexity. You can have a 20-line well-thought-out imperative Python script that is well-engineered. And you can have a 200,000 line Java app that leaks PII all over the place, loses user data twice a week, and is impossible to debug because it's a giant spaghetti rats nest.
