End of the day, it's just a big boiler; we invented it from scratch once, and it should be significantly easier to do it over again even if we do lose some knowledge. That said, the time to accelerate the industry really is now, before the situation gets any worse.

I think you're over simplifying things to the point far beyond what is useful to this conversation. While I disagree with the parent who is saying it is essentially a lost cause to restart the industry you go too far in the other direction suggesting it is a trivial endeavor, which misses all the complications that make them take years to build. Might as well say "End of the day, Google is just a text processor"
