When I see this kind of stuff I find them fascinating, because it's always the same story. People building a hardware product and then realizing that building hardware, even when it looks simple has a lot of moving parts. Coming back from that is quite impressive.
But when people boast about their amazing products to reek in VC money I actually get upset. I'm not sure if I'm more upset at the founders or the VCs though.
For example recently they have been raving about oxide, how amazing it is, how amazing the founder is, how amazing the idea is. But if you look at the website with all the ambitious goals and an estimate of early 2022[1] I can already see this company burning money like no other without ever getting close to that estimate. Either they have zero clue about supply chain or their wilfully misleading investors or a little bit of both.
But I guess that's the world we live in.
