Interesting question! My answer is maybe. A trading strategy can become obsolete if the market conditions or the trader's goals change significantly. So, it is important for traders to continuously reassess their strategy and make adjustments as needed in order to remain relevant and effective.

However, it is not necessarily the case that a trading strategy will always become obsolete, as some strategies may continue to be successful over longer periods of time.

These trading strategies that OP mentioned can only be obsolete when no one becomes a trader. Strategies can be improved in other ways but it doesn't mean that the old strategies are already useless. Traders have their own strategies, sometimes they created their own but guess what, it was mostly just a twist to the old one. We can say that the foundation is from the old one meaning traders still give value to them even though they are not using it literally.
