I know, and I am very excited for those languages to exist and be usable, and thereby have been tracking a couple such efforts; until then, this is about as useful as pointing out that website development is theoretically possible using a computer. The person did not state that it would always be the case that smart contracts are hard: only that right now, on Ethereum, they are hard, and the comment even used "gotten to the point where" (indicating this is a temporary state) and specifically blamed the "tools", which is all absolutely true and is born out not just in theory but in practice; it doesn't even disagree with your own statements that other different tools would be better. Why are you so defensive about this commentary?
Actually, I didn't mean to come across as defensive. I just like to nerd out about tech.
Once you accept the inherent craziness of the proposal, and go "Ok, this is crazy. What now?" you end up concluding that the future is going to be very interesting. It'd be worth investing some amount (that you can afford to lose!) in ETH on the off-chance that it doesn't suffer a major disaster. There are quite a few interesting applications for this technology, and historically that's been a pretty solid bet.
