We want developers to be able to psychologically leave ethereum, so we want to make their investment worth little.
Could you elaborate a bit? Core developers or people building on the platform?
Psychologically making people leave Ethereum and go to EOS, interesting strategy, but hopeful dreaming in my opinion.
I'll give a metaphor. Imagine the year is 1996. Ethereum might be Windows 95, compared to the future EOS being Mac OSX (assuming it's successful). If you invested in Microsoft in 1996, you would have made good profits and could have sold at the height of Microsoft. If you bought Apple in 1996, you would have a long time to wait before that company got itself positioned in the market properly.
Ethereum isn't the best, but it's running right now. It has solid foundations, it's improving steadily, and it's foundations getting stronger. Everyday new things are being built on on top of it.
EOS is a machine that doesn't exist yet. It's theoretically amazing, but it hasn't been tested. When it arrives, it will have nearly Zero foundations. How valuable is an amazing Operating System that has No applications built for it yet? Good applications take a long time to make, and we still have a year on top of that before anything really starts churning. Meanwhile, slow and steady Ethereum will have tons of new and cool things working with it's system.
So it seems impractical for people to "psychologically leave ethereum", when there is nothing to leave for. When EOS is finally released, it will be an amazing shiny new thing- and the average user won't be able to do anything with yet.
And all of this assumes the "Best Possible Scenario". No hiccups/hangups or problems with EOS. If there ends up being some unforeseen bug or flaw in the design, then things could get a lot worse. Just my crazy 2 cents, but I'll be staying far away from EOS for the time being...
