The Wright brothers made their first successful powered flight on December 17, 1903. Commercial air travel began to develop in the 1920s. 17 years. So you got that one right but that required major industrial tooling and production to happen to make the planes built which took longer than the time it took for them to be merely "possible".

The first mobile phone publicly available Motorola DynaTAC, was released to the public in 1983. Mass adoption of cell phones began in the 1990s. So only 7 years, also requiring advancements to be made to produce them and factories to start churning them out and distributing them.

Crypto infrastructure is already in place, no new tech or factories required. Only the mass adoption part, so one would expect the curve to be much shorter.

But as you know, from simply trying to get your hive out to a fiat currency, its many steps, many involved parties and fees along that path, slow depending on the chain/coin and exchange methods and regional rules and delays (aka bank EFTs taking 3 days blah blah)

So there is room for some "retooling" in that process though there are some easier, faster ways depending on the coin type - like BTC backed visa cards and stuff such as Bitpay cards, or SaaS platforms like robinhood or paypal whatever where you do your crypto buying and selling from a card attached account, but its still too complex for the proverbial "grandma can't program the microwave oven" types.

So I feel like you make a valid point, but there should still be faster, more widespread "mainstream" acceptance in 14 years for crypto, than compared to physical tech like planes and cell phones, because useful software can and often IS created literally overnight.
