This pick-n-place may not seem like a big deal to you, but it's important to remember these robots are not only working faster, they're working under tighter tollerances than a human is capable of. Each chip is perfectly installed on the board, in the correct position every time.
A human is much more prone to faults when performing this sort of manual labor with a miniature chip like the one in the hopper (remember each round chip is around 12mm in diameter).
Clearly this part of the build was extremely time consuming. Hence the investment in the machinery necessary to decrease production times and increase quality.
What I find interesting is that Hopper Labs has chosen to assemble these chips in-house. I'm sure these could have been mass produced in china at a lower per-unit cost. There must be some reason why they're doing it themselves - I'm guessing it's either for quality control reasons, or because that's a critical component of their device and they're protecting their intellectual property.
There is no way they were building those boards manually. My point is that they were paying someone else to stuff the boards before and whoever that was, was also using a pick n place. To me that means little if any improvement in board reliability, unless that supplier was just shit.
