Ya, that seems to be the most common use of "agree to disagree", at least that I've experienced. Someone won't bother to read what I wrote, or will sort of glaze over while I'm talking, then decide that we should just agree to disagree.
Oh ya, I mean we had awesome electric cars 120 years ago, of course the corporatocracy has allowed that sort of thing to get big... Though at the same time it's important to note that they usually shut these things down because the inventors are willing to sell it to them. If they weren't trying to get paid, the corporations wouldn't have control of so many patents.
Nowadays, every inventor who actually wants to help needs to be putting things out open source, and the more designs that can be 3D printed, the better it is for everyone on Earth.
Agreed I am a big fan of open source. i was so excited when I first cme to steemit because I was hoping we could foster alternative science here and engineering- finance it with steem on the contingency that everything developed would be open source .. sadly steem at this point in time is just a reflection of the outside world but I still hope that can be changed because the potential is there to be sooo much more ...
