Most of the us think that we know "things". We belittle other people's point of view. Doctors and politicians kept emphasizing flaw statistics, while they did not actually understand the whole problem. There's a saying "pride comes before the fall". We're not immune to this, lots of manufacturers and engineers also say "what's so difficult to make a ventilator?". We talk before we think - Tesla guy changed his mind from making ventilators to importing them.
We also have to be cautious to only listening to tech influencer. Past history does not mean future success. Trust your own smart judgement and survival instinct.
