True but we can have an outlook that the technology behind these Asic Miner will continue to get better producing more hash rate in a lesser energy consumption, thus making dollar spend much more efficient than the previous technology. this is another reason why the Bitcoin network hash rate history is consistently upward.
It is true that the technology behind Bitcoin mining hardware, including application-specific integrated circuits (ASICs), has improved significantly over time. This has allowed for more efficient mining operations, with newer hardware able to produce more hash rate with less energy consumption than older hardware.
However, it is important to note that the hash rate of the Bitcoin network is influenced by a variety of factors, and it is not necessarily a consistent upward trend. As I mentioned earlier, the hash rate can fluctuate due to changes in the price of Bitcoin, the availability and cost of mining equipment, electricity costs, and changes to the Bitcoin protocol.
While it is possible that improvements in mining hardware technology may contribute to an overall upward trend in the hash rate over the long term, it is not the only factor that determines the hash rate. It is therefore difficult to accurately predict how the hash rate will change in the future.
