How will a taproot upgrade affect bitcoin scalability?

As a keen observer of the cryptocurrency landscape, I'm particularly interested in understanding the potential impact of the Taproot upgrade on Bitcoin's scalability. Could you elaborate on how this upgrade is expected to enhance Bitcoin's ability to handle an increasing number of transactions? Will it improve transaction throughput, reduce latency, or perhaps optimize resource utilization? Moreover, how does Taproot's introduction of Schnorr signatures and Merkleized Abstract Syntax Trees factor into this discussion? Lastly, how might these improvements affect the user experience of transacting with Bitcoin, particularly in terms of speed, cost, and ease of use?
