The famous sociologist who argued that the use of machinery actually deskills workers is Harry Braverman.

Harry Braverman was an American Marxist sociologist known for his influential work titled "Labor and Monopoly Capital: The Degradation of Work in the Twentieth Century." In this book, Braverman critically analyzed the impact of capitalist production on workers and argued that the use of machinery and technology in the workplace ultimately leads to the deskilling of workers.

Deskilling of Workers:
Braverman's argument on the deskilling of workers stems from the idea that capitalism seeks to maximize profits by reducing labor costs and increasing efficiency. According to Braverman, the introduction of machinery and technology in the workplace allows capitalists to simplify and control the work process, thereby diminishing the skills and autonomy of workers.

Capitalist Control:
Braverman emphasized that capitalists have a vested interest in maintaining control over the labor process to ensure greater profitability. By breaking down complex tasks into simple, repetitive, and easily trainable actions, capitalists can easily replace skilled workers with less skilled or even unskilled laborers. This process of reducing tasks to their simplest components ultimately leads to the deskilling of workers.

Division of Labor:
Braverman also highlighted the role of the division of labor in the deskilling process. As machinery and technology become more prevalent in the workplace, the division of labor becomes more pronounced. Workers are assigned narrow and specialized tasks, limiting their exposure to the broader production process. This specialization further erodes their skills and knowledge, reducing them to mere cogs in the capitalist machine.

Alienation and Exploitation:
Braverman argued that the deskilling of workers contributes to their alienation from the labor process. As workers become detached from the overall production and lose control over their work, they experience a loss of job satisfaction and a sense of purpose. Additionally, capitalists exploit this deskilling by paying workers lower wages, as their easily replaceable skills command less value in the labor market.

Implications:
Braverman's analysis of the deskilling of workers has significant implications for understanding the dynamics of capitalist production and its impact on labor. It sheds light on the exploitative nature of capitalism and the ways in which technology and machinery can be used as tools of control and domination. Furthermore, it highlights the need for workers to organize and fight for their rights in the face of deskilling and alienation.

In conclusion, Harry Braverman, through his seminal work, argued that the use of machinery in capitalist production leads to the deskilling of workers. His analysis provides critical insights into the capitalist labor process, highlighting the exploitative nature of capitalism and the implications it has for workers' autonomy and job satisfaction.
