如果你掌握了一点三脚猫的算法，或者准确说是行业应用经验， 那也仅仅是掌握了一门得以糊口的技能而已。 护城河没多高，日常的辛苦工作仍然少不了。

人人都感慨工控行业的门槛低，哪怕学历不高，只要脑子灵活，勤学好问，肯动手，也很快能入门。 只要入得们来，稍微有些资历，工资就可以过万，这些人可以认为是不懂什么算法。 而这个行业中，能见到的的工程师，大概也就3万也就封顶了。

所以，相比于没有任何算法技能的一万元，三万元中所需要的算法技能也不会太多。 所以那些入门后以为通过再多掌握些算法，然后有可能获得高薪的，恐怕要失望了。

所以，我的观点是，所谓的算法， 在工控工程师中并不值什么钱。

还有一个佐证的例子。

有一位网友，搞农业温室的控制，疫情期间，一方面有些空闲，一方面项目中需要用到空气焓湿图的应用，然后他就自己把大学期间学的高等数学微分方程等技能再拾起来，把焓湿图的物理方程给计算解开了。
