The Ethereum platform was officially launched at July 30, 2015,[5] and is still in active development. One would think they would have already solved the Transactions Per Second issue. Let's be honest, 15tps is beyond pathetic and worse. Everybody would have assumed that it would be up to at least 500 to 1000 TPS by now. It's been 3 years. This is where EOS should shine bright, because EOS in 3 years to me looks like 50,000 up to 100,000+ TPS if not more. All while faithfully staying as Decentralized as they get. As the platform matures so should the speed & efficiency. ETH greatly lacks this and it will show in the coming years. ETH was a good proof of concept for it's time as a second generation blockchain with smart contracts, but it cannot be too easily upgraded.
This is why EOS will surpass it in the future because of the extremely high TPS and low block times it offers. EOS also has a governance model that allows for problems to be solved on-chain rather than having to rely on hard forking in the case of bugs or hacks.
