While it is a bit unfortunate that the time spent to write the article continues to be used as a criticism, and perhaps as a dig, I’ll only add that I have no formal background on type theory or logic. So much of the 15 months was also spent on learning the underlying concepts, mostly on my free time, and I am quite happy to even produce _something_ on a topic I have only recently got into. I am sure people smarter or more familiar with the theory than me would produce more in less time.
No, I was just joking in my last comment, as I know how time-consuming true progress can be. I'm also familiar with how type theory can overcomplicate simple things. When I see this happening, I can't help but point it out, although my criticism might seem out of context. I would be very happy if I could deliver tools for abstraction logic in just 15 months.
