Wow, an article full of baseless FUD. I would expect you to do some research instead of repeating misinformation. How disappointing.
Here's just one example.
"Finally, DAGs are fundamentally unable to do generalized smart contracts. It all happens due to the fact that IOTA doesn’t recognize the transaction order."
The Tangle already has time-stamps, so this is just wrong. Smart contracts are in active development and just around the corner. It's very understandable why Ethereum fan-boys would be shaking in their boots. They are still implementing PoS which the IOTA dev CfB invented years ago.
