To give him the benefit of the doubt, he seems to be writing to people wanting to make small electronic gadgets. You can't sell something for $19.99 retail that requires a lot of hands-on time. At a quick scan, Bolt.IO includes "Carbon Robotics - Building intelligent robots for agriculture-related applications", "Denizen - Personal prefab offices...", and "Spyce - An original restaurant concept featuring a robotic kitchen that cooks and serves delicious meals". I guarantee those robots, office furniture, and kitchens contain CNCed parts, if not hand-fitted parts. On the other hand, he also wrote "What happened when Apple wanted to CNC machine a million MacBook bodies a year? They bought 10k CNC machines to do it." If a CNC machine can't make more than one piece every 3.5 days, you're either building aircraft or you're doing it wrong.
