Jayvik and Arcane brain rot

Year 1 - Hexgate proof of concept developed and presented. Up to that point, Hextech exists and has Mel's support, but Jayce and Viktor still haven't proven themselves enough to get all the resources they'll need to build something like the Hexgates. The Distinguished Innovators competition takes place somewhere around this time. Maybe they presented the Hexgate proof of concept there (pure speculation on my part but you'll see why I think the first few years had to be laser focused on the Hexgates over anything else for any of this to make sense.)

Year 2 - Hexgates under development.

Year 3 - Hexgates under development.

Year 4 - Hexgates open to the world.

Year 5 - Hexgate distance capacity increased.

Year 6 - Events of Arcane

By the way, I say only one year to develop a prototype, it could have taken longer. But, the Progress Day post-time skip in 1.04 could be 7 years later. So all the approximations up there should be taken as "give or take a year".

Still, that means that within 3-4 years at most, Jayce and Viktor went from this proof of concept that Hextech is viable at all:

To this:

And can I say just as an archaeology nerd obsessed with stone crafting and material cultures, holy shit, do you have any idea how quickly they must have built the Hexgate tower to have it done in 2-3 years? The Empire State Building, which offers us a decent parallel for the technology available in the world of Arcane at this point, took a 1 year, 45 days, it was considered the fastest a skyscraper had ever been constructed at the time.

But the Hexgate tower is more than just a building, this thing goes all the way down into the bedrock, it is lined with Hex crystals. It has that giant globe on the top for pinpointing where to send the ship. It's not just a building, the entire thing is an engineering marvel. And it has to have been done in under 3 years to fit the most generous version of the timeline.

This would, realistically, require incredible buy-in by the entirety of Piltover society. We're talking multiple guilds vying for contracts, red tape being cut by the mile to secure the space, deep excavation beneath it, shipping to bring in materials, endless amounts of masons, metalworkers, and artisans. It's doubtful that Jayce and Viktor slept during those years. The sophistication we see within the Hexgates makes it even more mind-boggling.

Seriously, look at the base of this thing! This is the failsafe, it had to exist before they opened up the Hexgates to the world! It can't be an afterthought or a later addition!

And this Hex crystal-lined channel goes up for miles! (not literally but get my point) It needs sophisticated technicians to operate and switch out the cores!

Now, of course a Doylist explanation, the Hexgates are as sophisticated as they need to be and were built as quickly as they needed to be built in order to serve the plot, and Piltover is as technologically sophisticated as is needed for these to be built in the time required.

But, Watsonian, as someone who can't help but look at building materials and think about just how much time and effort it would take a society that looks vaguely 1880s-1920s (I would say the 1.04 Progress Day is deliberately invoking the Chicago World's Fair of 1893) it is utterly mind-boggling to me how much labor and materials and effort would have to go into building the Hexgates in a 2-3 year period. That's moon launch levels of an entire society mobilizing for one goal.
