The biggest barrier is Bitcoin Core's deliberately high fees.
Who is going to pay a $10 fee to buy a cup of coffee.
Of course Satoshi had the fee problem and scaling solved from day one but when Blockstream hijacked the GitHub repo they diverted BTC to have high fees in an attempt to push users to their second layer products like Liquid and LN.
You joke but none of these are passing fads. Bitorent continues to host and sever terabytes of data daily, I just downloaded my OS over torrent the other day. Bitcoin has been working great (now called Bitcoin Cash) as Peer to Peer Digital Cash for over a decade now. And ML makes EVERYTHING you do online possible. Try to image a modern search engine without ML.
There is no reason to joke about these life changing technologies unless you just don't understand how valuable they are.
I make payments almost everyday with Peer to Peer Digital Cash. Real users and devs moved to other projects like Bitcoin Cash, Ethereum and Monero soon after Blockstream hijacked the Bitcoin Core GitHub repo.
Bitcoin Core is broken beyond repair but Bitcoin Cash has taken its place and the project and community are doing great.
