Lovelace and Meteor Lake are going to kill the high-end laptop market.
We're already beyond the point of "reasonable" power draw with high end Ampere and Alder Lake. Both successors are likely to increase this by 50% or more which will change things from "unreasonable" to "ridiculously stupid".
Edit:
Another thought on this - how is a watercooling system for an internal GPU any better than an eGPU in a dock? Once disconnected, the laptop is restricted in its capabilities either way but with an eGPU at least you can have a laptop that's relatively thin and portable with long battery life - something that's impossible if you're carrying around all of the heatsink and power delivery for a hungry desktop CPU and 3080Ti.
Moving the cooling system to the dock just means that when you do actually need portability you're forced to carry around a chunky plastic laptop with parts that have high power draw and are unsuitable or at least a poor choice for running off the battery in the first place. The air-cooling abilities of the laptop are somewhat compromised by the addition of (now non-functional) watercooling hardware. The double-stacked pipes in the cooling system (water pipe on top of heatpipe) mandates extra-flat, less effective heatpipes in the first place, and strictly rules out the option of a slimmer, lighter device.
