Model Slimming Beats Muscle Building for Profit

After doing investment for a long time, I increasingly feel that AI models are somewhat like selling cars. You spend several million to buy a Porsche 911, with explosive performance, but during daily commutes in traffic jams, you step on the gas and then immediately hit the brakes, so most of the horsepower goes unused. Now someone tells you, "I've shrunk the Porsche engine to one-quarter size, acceleration from 0 to 100km/h is only 0.5 seconds slower, and the price is just one-tenth." Would you buy it?
