My two cents: We've been waiting for a non-speculative use for ethereum since 2013. After how many years might it be time to suggest that there is no non-speculative use?
It will naturally die if/when all ideas have been extinguished, and we all should hope no sooner. This is literally the process all invention goes through, some tech just more publically visible than others. What do you think?
I have been getting a number of people trying to get me to apply for crypto jobs recently. They list a load of buzzwords expecting me to be enthusiastic about the hot new tech. I explain that I am not (but that I will work for them if they are interested in a solid software engineer and they pay me enough).
