The article doesn't make much sense. It starts with the author saying the IOTA whitepaper was indecipherable, that the language choice was a bad idea, the code is undocumented etc. and then (ignoring massive red flags like the IOTA devs creating their own hash function) the author bought into and sold out of IOTA multiple times while experience major issues. Personally I think C++ is a bad choice. A safer language that is easier to verify is preferable when small bugs have the potential to wipe out a cryptocurrency. Imagine Bitcoin got hit with a bug that allowed wallets to be emptied or took down the network such that a hard fork was required to fix it; it would wipe out confidence if this happened enough times. Maybe I'm missing something beyond the developers being very disciplined but I'm impressed this hasn't happened yet.
