First of all, I make product decisions for a very large real estate tech company. If you’ve looked up houses for sale online in the last 15 years, you used a product I made a ton of decisions on.
Second, you use extreme examples like floppy disks. Let’s be reasonable here. There’s tech better than USBC out there today. Why don’t we just deprecate USBC in 2021? Oh right, there’s more to adoption than superior tech.
Third, you make progress in tech industry by fulfilling a customer demand.
Lastly, as stated many many times in this forum now, USB-A is actually much more popular than USB-C today. So USB-C is actually the niche.
