Even if we assume you are right (and I vehemently think you are not) regarding never taking significant business from the legacy manufacturers, they are being forced, through customer expectation into a realm they are completely and utterly unable to compete in. Just look at the real world specs on the IPace and other "Tesla Killers" they are desperately trying to throw into the market. Yes, eventually they will figure it out...but when? And the most important question will be where is Tesla at that point? You think they are going to be static in their drive to lower cost and increase technological advancement? One thing that is universally accepted regarding the legacy manufacturers is that while they have gotten very good at making cars, they absolutely, positively SUCK at software. How are they going to catch up in a field that they know virtually nothing about? They can't make a competitive alternative to a Tesla for a profit now. How are they going to do it when Tesla keeps driving down their own battery costs and advancing software features (like autopilot) that the others have absolutely no clue how to replicate...let alone for a profit?
They are on a sinking ship, and I think they know it. Some will be able to scrape by perhaps but many will not. There is such a gap between them and Tesla, and the buying public is consistently showing that what Tesla has is what they want. I just don't see them realistically ever catching up. But...I guess we'll see.

You seem the operate on the assumption that cars such as I-Pace are supposed to be the absolute best the legacy car makers can achieve. It's not a best effort. Maybe for Jaguar, but they are not exactly tech leaders (anymore).
It's simply not in the best interest for the industry for any BEV to be made that's ultimately appealing to consumers TODAY. Not even if all brands merged and focused on making that one desirable vehicle, they would never be able to make enough of them as they need to build new tooling and source batteries. It takes investment and/or sacrificing production lines needed for other cars that already sell and keep jobs covered.
Had I-Pace been 25% less energy thirty, charging at 250 kW and costing $50K, they'd only had a long waiting line, no extra income. Selling the design to other brands would still not have saved anyone from losing business. The way Model S and X buyers are not sitting on their money waiting for an upgrade, the whole market would crawl to a halt limited by BEV supply. That would cost hundreds of thousands of jobs, basically overnight.
And if legacy car makers were so foolish to make that compelling one car, losing so much business, would Tesla pick up that business? No. They can't make Model 3 any faster than they did now 10 months ago.
The still petrol based industry is trying to get a gradual transition going. Not exposing BEVs greatness too quickly. Not building too many hyper fast chargers. Not because they could never build a compelling BEV, but because it would be like jumping a meter up from joy right into noose.
Tesla is making the others look foolish, but only to that small group of hippies and some really open and clear minded car nerds who can also see Tesla's deficiencies and view the world a bit differently than the average readership on BEV sites.
I have good hopes Porsche Taycan will hold fewer punches. It's been a long time coming and they are readying themselves to replace a good amount of petrol car sales to be lost, or even grow overall. Sounds easy, but it's really hard, even for a smaller premium brand like Porsche.
The software thing... Tesla showed promise, but in my opinion didn't quite deliver, especially on its own promises, let alone based on the architecture effected. What would have been a good year to launch an app store, allow external designers come up with new screen interfaces to sell to the public over the Tesla App Store? I think 2016 would have been acceptable. Now, we get some Easter eggs and seeing charge speed in both kW and mph is still too much to ask. Where is Nerd Mode, huh?
Vital difference between legacy car makers and Tesla is that other brands make a car that their customers want to buy. Tesla seems to change as much to that as they can get away with. Maybe too much. It's seen in the smallest details that are blatantly obvious, cost 10.000's if not 100.000's of sales, but for which Tesla happily takes out 7-8 years to fix. Towing, Estate, how much would that cost now, really? That's what many people who don't have a Tesla yet but could swing that, actually want. Soon there will be a whole generation that could buy 3 or Y but just prefers an instrument cluster and gets themselves on a reservation list for Polestar, Volvo, BMW, etc.
