Why are disruptive technologies "tricky"? Provide examples

What will be an ideal response?

Disruptive technologies can be tricky because firms that invent disruptive technologies as first movers do not always benefit if they lack the resources to exploit the technology or fail to see the opportunity. For example, the MITS Altair 8800 is widely regarded as the first PC, but its inventors did not take advantage of their first-mover status. Second movers, so-called fast followers such as IBM and Microsoft, reaped the rewards. Citibank's ATMs revolutionized retail banking, but other banks copied them. Now all banks use ATMs, and the benefits go mostly to the consumers.
