What you're saying resonates for so many new products. I find that most time or labor saving ideas save time on something that is not actually the problem, or address a charicature of the actual workflow. I dont think it means we should give up and stop trying, rather that its critical to test with real users IMO before trying to sign deals on a product that doesn't make sense.
And sometimes the things that are automated were the only thing that was pleasant. It's not true for laying bricks because the heavy lifting makes it unpleasant.
I have never laid brick but I've done a lot of shingled roofs. The "fun" part of shingling is long stretches of full sheets in the middle of the roof. This goes quickly and is rewarding. The less fun, and what occupies the time, is where there is a chimney or a valley or a dormer or some other feature that you need to figure out and cut some flashing for, and custom fit each shingle that butts up against the feature, seal with tar sometimes, etc.
I picture a lot of automated solutions focusing on the "in the field" part where the work is easy and rewarding, and glossing over the manual intervention and craftsmanship that is needed for all the nonstandard bits. I don't know about bricklaying though I imagine it has similar characteristics, where a square windowless wall goes very fast, and could be pleasant work, and all the time is spent dealing with windows and the frame not being level and other edge cases.
Yes agreed, sorry I was thinking in terms of a new product, testing the value prop with users, which is probably better stated as requirements gathering.
